The 19th International Workshop on Neutrinos from Accelerators (NUFACT2017)

Europe/Stockholm
Uppsala University Main Building

Uppsala University Main Building

Biskopsgatan 3, Uppsala
Description
NUFACT2017 is the nineteenth in the series of yearly international workshops which started in 1999 and which until now was called International Workshop on Neutrino Factories. The change of name to International Workshop on Neutrinos from Accelerators is related to the fact that the workshop program has, over the years, come to include all current and future accelerator and also reactor based neutrino projects, including also muon projects, not only the Neutrino Factory project. The main goal of the workshop is to review the progress of current and future facilities able to improve on measurements of the properties of neutral and charged lepton flavor violation, as well as searches for new phenomena beyond the capabilities of presently planned experiments. The workshop is both interdisciplinary and inter-regional in that experimenters, theorists and accelerator physicists from the Asian, American and European regions share expertise with the common goal of reviewing the results of currently operating experiments and designing the next generation of experiments. The NUFACT 2017 workshop is divided into five Working Groups covering the following topics: Working Group 1: Neutrino Oscillation Physics Working Group 2: Neutrino Scattering Physics Working Group 3: Accelerator Physics Working Group 4: Muon Physics Working Group 5: Neutrinos Beyond PMNS. This workshop is sponsored by the Nobel Committee for Physics and co­organized by the EuroNuNet COST Action. Contact: NUFACT2017@physics.uu.se

        Recent Results from the MINERvA Experiment 30m
        The MINERvA experiment, located in the NuMI beamline at Fermilab, is a dedicated neutrino scattering experiment. That main goal is make high precision measurements of neutrino interaction cross sections in the 1 to 20 GeV energy range, to support current and future oscillation experiments. MINERvA also provides information about the structure of protons and neutrons, and the dynamics that affect neutrino-nucleus interactions. The heart of the MINERvA detector is a fine-grained scintillator tracking chamber, surrounded by electromagnetic and hadronic calorimeters. Carbon, Iron and Lead targets are used to study the effect of the nuclear medium on neutrino-induced interactions. This talk presents a summary of the more recent MINERvA results.

        Status and prospects of charged lepton flavor violation searches with the MEG-II experiment 24m
        The MEG experiment took data at the Paul Scherrer Institut in the years 2009-2013 and published the most stringent limit on the charged lepton flavor violating decay $\mu \rightarrow e \gamma$: BR($\mu \rightarrow e \gamma$) $<4.2 \times 10^{-13}$ $@90\%$ C.L. The MEG detector is currently being upgraded in order to reach a sensitivity of $\sim 4 \times 10^{-14}$, which corresponds to an improvement of one order of magnitude. The basic idea of MEG-II is to achieve the highest possible sensitivity by making the maximum use ($7\times10^{7}$ muons/s) of the available muon intensity at PSI with an improved detector, keeping the background at a manageable level. The status of the MEG-II detector and the current schedule will be presented. MEG-II, together with the next generation charged lepton flavor violation experiments Mu3e ($\mu^+\rightarrow e^+e^-e^+$) at PSI and Mu2e and COMET ($\mu \rightarrow e$ conversion) at Fermilab and J-PARC respectively, will reach very high sensitivities in the next years. Accelerator upgrades are also expected, that will make muon beams with intensities of the order of $10^{10}$ muons/s feasible. At this extremely high beam rates, new detector concepts should be adopted for $\mu \rightarrow e \gamma$ searches, in order to overcome the accidental background. Some future directions will be discussed.

        Searching for Lepton-Flavour Violation with the Mu3e Experiment 24m
        The upcoming Mu3e experiment searches for the lepton-flavour violating decay $\mu^+\rightarrow e^+e^-e^+$ with the aim of a final sensitivity of one signal decay in $10^{16}$ observed muon decays, an improvement over the preceding SINDRUM experiment of four orders of magnitude. In the first phase, the experiment will be operated at an existing intense muon beam line at the Paul-Scherrer Institute. With muon stopping rates of about $10^8\text{s}^{-1}$, a single-event sensitivity of $2\cdot 10^{-15}$ can be achieved. For the ultimate sensitivity, a new high intensity muon beam line is required. In order to suppress background, the tracking detector is designed to measure low momentum electron and positron tracks with excellent precision by making use of very thin silicon pixel sensors. In addition, scintillating fibres and tiles provide precise timing information. Currently, the collaboration is finalizing the detector design and preparing for construction and commissioning. The experimental concept with focus on the tracking detector will be outlined and the current status as well as recent simulation results will be presented.

        Mu2e: Using Rare Muon Decays to Probe the Energy Frontier 24m
        The Mu2e collaboration proposes to search for coherent, neutrinoless conversion of muons into electrons in the field of a nucleus with a sensitivity improvement of a factor of 10,000 over existing limits. Such a lepton flavor-violating reaction probes new physics at a scale unavailable by direct searches at either present or planned high energy colliders. The physics motivation for Mu2e will be presented, as well as the design of the muon beamline and spectrometer. The scheme by which the experiment is to be mounted in the present Fermilab accelerator complex will be described, and the present status of the experiment will be given.

        COMET muon conversion experiment in J-PARC 24m
        COMET is an experiment at J-PARC, Japan, which will search for neutrinoless conversion of muons into electrons in the field of a nucleus ($\mu$+N$\to$e+N); a lepton flavor violating process. The experimental sensitivity goal for this process is of order 10$^{-15}$ for Phase-I and 10$^{-17}$ for Phase-II experiment, which is a factor of 100 to 10,000 improvements correspondingly over existing limits. Recent progress in facility and detector development will be presented. The COMET Phase-I experiment has received stage-II approval by the J-PARC PAC, and the future schedule for the start of data taking in 2018 will also be presented.

        Towards realising PRISM based muon to electron conversion experiment 24m
        To maximise discovery potentials of next generation lepton flavour violation experiments high intensity and high quality muon beams are required. Such beams can be produced by sending a short, high intensity proton pulse to the pion production target, capturing pions and collecting the resulting muons in the large acceptance transport system. By applying the RF phase rotation on the muon beam in the dedicated FFAG ring, proposed for the PRISM project, the beam quality can be substantially increased in terms of the momentum spread and purity. The parameters of the required proton beam, the principles of the PRISM experiment and the ring FFAG design are discussed. The spectrum of alternative designs for the experiment are shown. Progress on accelerator systems like beam transport, injection and RF are discussed. The current status of the study and its future directions are presented.

        Looking for Sterile Neutrinos via Neutral-Current Disappearance with NOvA 30m
        Three-flavor neutrino oscillations have successfully explained a wide range of neutrino oscillation data. However, the excess of events as seen by the LSND and MiniBooNE experiments and the deficit of events seen at the GALLEX and SAGE experiments when exposed to a calibration source can be interpreted as short-baseline neutrino oscillations consistent with the existence of a sterile neutrino state with a mass near 1 eV. While these results are tantalizing, they are not conclusive, as they are in tension with null results from other short-baseline experiments and disappearance searches in long-baseline and atmospheric experiments. Resolving the issue of the existence of light sterile neutrinos has profound implications for both particle physics and cosmology. The NOvA (NuMI Off-Axis $\nu_{e}$ Appearance) experiment may help clarify the situation by searching for disappearance of active neutrinos from the NuMI (Neutrinos from the Main Injector) beam over a baseline of 810 km. In this talk, I will present the latest results from NOvA on searching for oscillations of active neutrinos into sterile neutrinos by looking for a deficit of neutral current events relative to expectations.

        Latest Results from MINOS+ on Sterile Neutrinos, and Combined Analysis of MINOS, Daya Bay and Bugey-3 30m
        The MINOS/MINOS+ long-baseline neutrino experiment operated at the Fermi Laboratory between 2003 and 2016. The experiment was situated along the central axis of the NuMI accelerator neutrino beam, and comprised a pair of kiloton-scale steel-scintillator detectors, located 1km and 735km downstream of the beam target. MINOS accumulated in excess of 15e20 protons-on-target (POT) using a low-energy beam; MINOS+ subsequently collected a further 10e20 POT using a medium-energy beam. Both MINOS and MINOS+ have made precise measurements of three-flavour neutrino oscillations, and have also performed searches for new physics beyond the standard model of neutrino oscillations. In particular, both phases of the experiment are sensitive to sterile neutrinos in the region of parameter space favoured by the LSND and MiniBooNE experiments. In this talk, I will present the latest sterile neutrino results from MINOS and MINOS+, which are based on a 3+1 model, and combine both charged-current and neutral-current data in a two-detector analysis of neutrino disappearance. I will also discuss a combined analysis of the MINOS accelerator data with the Daya Bay and Bugey-3 reactor data, which has yielded strong constraints on anomalous muon to electron neutrino appearance. In addition to these results, I will present the latest direct searches by MINOS+ for sterile-driven anomalous appearance of electron neutrinos.

        Neutrino cross-section measurement prospects with SBND 30m
        SBND (Short-Baseline Near Detector) is a 112 ton liquid argon TPC neutrino detector under construction in the Fermilab Booster Neutrino Beam. Together with MicroBooNE and ICARUS-T600 detectors, SBND will search for short baseline neutrino oscillations in the 1 eV$^2$ mass range. SBND will also perform detailed studies of the physics of neutrino-argon interactions, thanks to a data sample of millions of electron and muon neutrino interactions. Finally SBND plays an important role in the on-going R&D effort to develop the LArTPC technology, testing several technologies that can be used in a future kiloton-scale neutrino detectors for a long-baseline experiment. We will discuss the detector design, its current status, and the physics program, with a particular focus on the neutrino cross-section measurement prospects.

        Pion scattering with the LArIAT experiment 30m
        This talk presents studies of pion scattering on liquid argon (LAr) with the LArIAT experiment. Pion scattering cross-sections on LAr are an important input to models of neutrino scattering used by current and future LAr neutrino experiments, such as MicroBooNE, SBND, and DUNE. LArIAT is a small LAr time projection chamber (LArTPC) in an instrumented test beam at Fermilab. The precise calorimetry and tracking of LArTPC technology enable reconstruction of an interacting pion's energy as well as identification of secondary particles produced in the interaction. This enables the measurement of the total pion-argon cross-section and exclusive interaction channels such as pion absorption, charge exchange, and scattering.

        We revisit charged lepton flavor violating (CLFV) scattering processes $\ell_{i} N \to \tau X \, (\ell_{i} \ni e, \mu)$ mediated by Higgs. We point out that a new subprocess $\ell_{i} g \to \tau g$ via the effective interactions of Higgs and gluon gives the dominant contribution to $\ell_{i} N \to \tau X$ for an incident beam energy of $E_{\ell} < 1\,\text{TeV}$ in fixed target experiments. Furthermore, in the light of quark number conservation, we consider quark pair-production processes $\ell_{i} g \to \tau q \bar{q}$ ($q$ denotes quarks) instead of $\ell_{i} q \to \tau q$. This corrects the threshold energy of each subprocess contributing to $\sigma(\ell_{i} N \to \tau X)$. Reevaluation of $\sigma(\ell_{i} N \to \tau X)$ including all of relevant subprocesses shows that the search for $\ell_{i} N \to \tau X$ could serve a complementary opportunity with other relevant processes to shed light on the Higgs CLFV.

        Construction of new DC muon beamline, MuSIC-RCNP, for muon applied science 23m
        A new DC muon beamline, MuSIC (MUon Science Innovative muon beam Channel) was constructed at Research Center for Nuclear Physics (RCNP), Osaka University. The MuSIC is a versatile beamline for various experiments in a fundamental physics and a muon applied science. This beamline provides intense positive and negative muon beams from 28 to 110 MeV/c. It is designed to provide an intense muon beam by a novel method with a pion capture superconducting solenoid magnet and a pion transport magnet. They enables us to collect pion very efficiently with very large acceptance. At present, the beamline is extended with several conventional magnets to an experimental port located at 22 m downstream of the production target to perform experiments. The beamline commissioning was started for investigating and optimizing the muon beam transport, beam parameters and background condition. Some experiments especially with negative muons were performed in parallel to the commissioning. In this presentation, we will report the MuSIC beamline and current status of the muon beamline commissioning and comment for future prospects in the MuSIC beamline.

Upper limits on the rate of the charged kaon decay into a muon and a heavy neutral lepton (HNL) obtained from 2007 data and limits for electron and heavy neutral lepton obtained with 2015-16 data, are reported for a range of HNL masses.

        ENUBET: high precision neutrino flux measurements in conventional neutrino beams 30m
        The precision era of neutrino physics requires measurements of absolute neutrino cross sections at the GeV scale with exquisite (1%) precision. These measurements are presently limited by the uncertainties on neutrino flux: the goal of the ERC ENUBET Project is to demonstrate that such uncertainties can be removed employing novel monitoring techniques of the leptons at the neutrino source. In particular, a reduction of these systematics by one order of magnitude can be achieved monitoring the positron production in the decay tunnel originating from the K_e3 decays of charged kaons in a sign and momentum selected narrow band beam. In this talk we present the results obtained during the first year of the Project on beamline simulation, rate and dose assessment, detector prototyping and evaluation of the physics reach. In particular, we present the Reference Design issued by the Collaboration in spring 2017, discussing its achievements and the remaining technical challenges.

        EMuS in CSNS 30m
        MuSR is a useful tool which use muons as magnetic probes in matter. There are several MuSR running around world. Now a R&D program named EMuS had been approved to setup a new MuSR in China. The EMuS will be located in CSNS, Dongguan. Use 4KW/20KW 1.6GeV proton beam from CSNS hit target to generate surface muons and pions, then secondary particels will be collected and transfered. Besides polarized muons used as MuSR, neutrinos decayed from pions and muons are planned to be used to do various experiments. Unlike those previous MuSR, EMuS adopted adiabatic particle capture system concept from Neutrino Factory and COMET, so a higher intensity muon beam is expected to be achieved. This would make EMuS a place with good competitiveness for material analysis and neutrino physics. Recent progress on design of the proton beamline, target station, MuSR beamline, neutrino muon beamline and MuSR will be reported.

        Search for lepton favour violation with the ATLAS detector 30m
        Lepton flavor violation (LVF) is a striking signature of potential beyond the Standard Model physics. The search for LFV with the ATLAS detector is reported in searches focusing on the decay of the Higgs boson, the Z boson and of a heavy neutral gauge boson, Z', using pp collisions data with a center of mass energy of 8 TeV and 13 TeV.

        Search for heavy neutrinos and charged lepton flavour violation processes at CMS 30m
        In the standard model (SM), charged lepton flavour violation (LFV) induced by neutrino oscillations is extremely suppressed. However extensions of the SM may enhance LFV processes to levels observable at the LHC. The talk will present the latest results on searches for heavy neutrinos and charged LFV processes performed by the CMS experiment at the CERN LHC collider. The searches are based on the analyses of proton-proton collision data collected in 2015 and 2016 at 13 TeV and corresponding to an integrated luminosity up to 36/fb. First, an update of the search for LFV decays of the H boson to mu-tau and e-tau finale states will be presented, based on the full 2016 dataset. These analyses superseed the ones performed on the 8 TeV data (collected in 2012) where a 2.4 sigma excess was observed in the H to muon-tau decay channel. A search for heavy resonances decaying to an electron and a muon in the final state will be detailed. Finally, results of the searches for a heavy neutrino in various final state topologies will be summarized.

        GENIE models and global fits of neutrino scattering data 30m
        Neutrino Monte Carlo generators are the single interface between theory and experiment and, as such, they are an essential ingredient in any attempt to connect neutrino data with the answers to fundamental physics questions. GENIE is the world's most widely-used neutrino Monte Carlo generator. Indeed, its physics model is employed by nearly all current and near future experiments. A key ingredient of the current effort to overhaul the GENIE phenomenological descriptions of neutrino scattering is to develop the capability to perform a global physics tuning using both the increasing body of neutrino scattering data and the vast complementary array of electron-nucleus and hadron-nucleus scattering data. GENIE already contains extensive curated data archives and, quite uniquely, it can simulate the nuclear scattering of neutrinos, electrons and hadronic probes in the exact same physics framework. The vast set of GENIE comparisons to published data, along with GENIE machinery that allows the efficient incorporation of physics uncertainties in the GENIE predictions, will underlie the global tuning effort. A new collaboration with the Professor system authors used for Monte Carlo generator tuning for the Large Hadron Collider (LHC) experiments, provides the main algorithmic procedure for obtaining new physics tunes. In this talk we will outline the development of GENIE models for the simulation of CC $0\pi$ events (a crucial event topology both for oscillation measurements and for probing nuclear dynamics) and present results of the first GENIE global fits of CC $0\pi$ data.

        Understanding the structure and the electroweak interactions of atomic nuclei in terms of their individual constituents is an intriguing nuclear many-body problem. In addition, precise measurements of neutrino oscillations require a quantitative understanding of neutrino-nucleus interactions. I will show how quantum Monte Carlo allows to consistently describe the structure of atomic nuclei and their interaction with electroweak probes, providing a reliable estimate of the theoretical uncertainty of the calculation. I will focus on the electromagnetic and neutral-current response functions of $^{12}$C, discussing the effect of two-body currents and the role of relativistic effects in correlated nuclear systems.

        Update on MOMENT target station studies 30m
        The muon decay medium-baseline facility (MOMENT) is a high intensity neutrino beam proposed in China, aiming to measure leptonic CP violation. The primary proton beam has 15 MW of power provided from an ADS type of linac, which poses a radiation challenge to a capture system that consists of an adiabatic superconductive solenoid from 14 T to 3 T, and a high power liquid or fluidized target located inside the main capture coil in order to maximize the pions capture and reduce their transverse momentum. Though the initial baseline is the liquid Hg-jet, a novel fluidized waterfall-like granular target is also being studied. In this paper, we present updated studies for the waterfall granular target concerning simulations done with Discrete Element Method and particle physics Monte Carlo analyses. Our aim is to calculate the optimal physical parameters of the waterfall in order to comply with the physics (captured meson yields) requirements of MOMENT, to remove the heat efficiently, and finally to compare the radiation damage caused on the shields of the solenoid with the case of liquid Hg-jet that is severe.

        The Muon g-2 Experiment at Fermilab will measure the anomalous magnetic moment of the muon to a precision of 140 parts per billion, which is a factor of four improvement over the previous E821 measurement at Brookhaven. The experiment will also extend the search for the muons electric dipole moment (EDM) by approximately two orders of magnitude. Both of these measurements are made by combining a precise measurement of the 1.45T storage ring magnetic field with an analysis of the modulation of the decay rate of the higher-energy positrons from the (anti-)muon decays recorded by 24 calorimeters and 3 straw tracking detectors. The current status of the experiment as well as results from the initial beam delivery and engineering run in the summer of 2017 will be described.

New E34 measurement at J-PARC uses a novel technique of ultra-cold muon beam. Ultra-cold muons are generated from high intensity surface muons by thermal muonium production and laser ionization. After acceleration to 300 MeV in muon linac, the beam is injected and stored in a circulating orbit in an ultra-high precision MRI-type magnet for g-2/EDM measurement. Thus, it is quite complementary to the measurement at BNL and FNAL. The overall design and its preparation status will be reported.

The year 2017 marks the beginning of DUNE civil construction at SURF. Physics with the DUNE far detector is expected to start in 2024, while first neutrino beam from FNAL to SURF is expected in 2026. During this talk I will focus on two aspects. First, I will discuss the DUNE projected physics reach, with a focus on long-baseline neutrino oscillation physics. Second, I will describe the DUNE/LBNF project status, with an emphasis on the design of the far and near neutrino detectors and on the related prototyping activities.

        Neutrino-nucleus interactions at intermediate energies 30m
        Present and future generations of accelerator-based neutrino-oscillation experiments use nuclei as targets, therefore, a good understanding of neutrino-nucleus processes is essential to reduce systematic errors in the oscillation analyses. In addition to that, since monoenergetic neutrino beams are not available, the theoretical models have to be able to describe all possible reaction channels in the wide energy region covered by the beam: quasielastic scattering, two-body current contributions, single-pion production, deep inelastic scattering, etc. In recent years, the research activities of the Ghent group have focused on providing a consistent description of some of these mechanisms. We wish to present the current status of our investigations. We describe the low energy region with collective nuclear excitations and the quasielastic peak using a Hartree-Fock-CRPA (continuum random phase approximation) model that takes into account nuclear long-range correlations as well as hadronic final-state interactions. The two-body current mechanisms, which are especially important in the region between the quasielastic and the delta-resonance peak, are treated within the same mean-field based model. We consider the influence of nuclear short-range correlations on one- and two-nucleon knockout channels. Our description of intermediate-energy neutrino-nucleus scattering is completed by modeling neutrino-induced single-pion production. For that, we consider resonance decays as well as other contributions required by chiral symmetry. This low-energy model is combined with a Regge approach, that allows us to extend our predictions beyond the resonance region.

In particular, we discuss the weak excitation of two-particle-two-hole (2p2h) states induced by meson exchange currents and illustrate the role of relativistic effects, quantify the size of the direct-exchange interferences, and the relative importance of the axial versus vector current. The model is validated versus all available electron-carbon scattering data and its predictions are compared with neutrino scattering data from MiniBooNE, MINERvA, T2K and NOMAD. The results of a recent study on the density dependence of the 2p2h response are also presented and discussed.

        Semi-phenomenological spectral functions in neutrino-nucleus inclusive reactions 30m
        In order to develop a reliable model for neutrino-nucleus interaction, one has to account for various nuclear effects which go beyond Fermi gas picture. In this talk I will present a recent study of neutrino-nucleus inclusive reactions at low and intermediate energies where in medium modifications are introduced in terms of the hole and particle semi-phenomenological spectral functions (SFs). Concentrating on the quasi-elastic mechanism, I will show how SFs are included into the particle-hole propagator (which is the basic notion in our approach). I will also describe the interplay of RPA effects (which are crucial part of the model developed by Valencia group) and SFs. Finally I will present results (and comparisons with other approaches) for both neutrino and antineutrino CC quasi-elastic processes for various targets and energies.

        The ESSnuSB Accumulator 30m
        The 2.0 GeV, 5 MW proton linac for the European Spallation Source, ESS, would have the capacity to send extra pulses to a neutrino target, giving an excellent opportunity to produce a high performance neutrino beam, the ESS neutrino Super Beam (ESSnuSB). The neutrino target focusing system needs pulses shorter than a few micro-seconds. These short pulses will be formed in an accumulation ring, handling 2.86 ms long linac pulses with 1.1E15 protons in each pulse. One of the main challenges of this accumulator ring is the injection of the particles. H- stripping and painting is the method worked on presently. Some other ideas like lossless, multi-turn and multi-plane injection of protons could will also be investigated. The evolution of the beam distribution is studied during accumulation in order to make sure the beam characteristics meet the requirements from the extraction region, the transfer line and the target system. Simulation results and plans for future work on the accumulator design in view of the ESSnuSB design report will be discussed.

        Prospects of LFV studies at Belle II 24m
        The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK ``B factory'' facility in Tsukuba, Japan. The machine is designed for an instantaneous luminosity of 8x10^35 cm^-2s^-1, and the experiment is expected to accumulate a data sample of about 50 ab^-1 in five years of running. With this amount of data, decays sensitive to physics beyond the Standard Model and cLFV can be studied with unprecedented precision. One promising set of modes are physics processes containing neutrinos which are characterized by missing energy. Topics which will be discussed are: Lepton number violation in τ decays, Violation of lepton universality in b➝c(τ/l)ν, Violation of lepton universality in b➝sll

        Precision measurement of muonium hyperfine structure at J-PARC 24m
        Muonium is the bound state of a positive muon and an electron. Muonium is free from the finite-size effect of nucleons, thus the theoretical value of muonium hyperfine splitting (MuHFS) can be detemined precisely. MuSEUM (Muonium Spectroscopy Experiment Using Microwave) aims ten-fold improvement of the preceding measurement of the experimental value of MuHFS in the ground state both in zero magnetic field and in high magnetic field. This can be achieved by using the most intense pulsed muon beam supplied at J-PARC MLF MUSE.  The procedure of this measurement is as follows :   1. Spin polarized muons are injected to a RF cavity filled with Kr gas, which is covered with magnetic shields or a superconducting magnet.   2. Muonium is formed via electron capture in Kr gas and its HFS transition is induced by RF field.   3. Spectroscopy of MuHFS is performed by the measurement of angular asymmetry of decay positron from muon decay.  In this presentation, I report the result of the MuHFS mesurement in zero magnetic field and future prospect.

        Development of the magnetic field mapping method for the precise spectroscopy of the muonium hyperfine splitting with 1.7 T magnetic field 24m
        Muonium is a hydrogen-like atom formed by a positive muon and an electron. The measurement of muonium hyperfine structure (MuHFS) at ground state is a good probe to test the theory of the bound state quantum electrodynamics (QED). Moreover, from the MuHFS measurement with high magnetic field, the muon-to-proton magnetic moment ratio and mass ratio are also derived. As the muon-to-proton magnetic moment ratio is an important input parameter for the muon anomalous magnetic moment ($g − 2$), the precision of the MuHFS measurement is also important for the ($g− 2$) measurement, which is known for about $3$ standard deviation ($3\sigma$) discrepancy between the standard model prediction and the experimental value [1] [2]. The current value of MuHFS was measured in $1.7$ T magnetic field with a precision of 120 ppb and μμ/μp, mμ/mp were in $12$ ppb [3]. However, the biggest uncertainty in the previous measurement was caused by the statistics and the second was systematical uncertainty caused by the magnetic field inhomogeneity. MuSEUM (Muonium Spectroscopy Experiment Using Microwave) collaboration is planning to improve this precision by a factor of 10 by using the intense pulsed muon beam at J-PARC MLF and suppressing the magnetic field inhomogeneity. To suppress the systematic uncertainty caused by the magnetic field inhomogeneity, we are developing the magnetic field mapping method to scan the magnetic field in the muonium production region with a high precision.

        Precision laser spectroscopy of the ground state hyperfine splitting in muonic hydrogen 24m
        The proton is a fundamental constituent of the world. However, its internal structure has not been fully understood because of the complicity and difficulties in both theory and experiment. In 2010, a significant discrepancy between two independent measurements of the proton charge radius was reported. This conflict is known as "proton radius puzzle". Even though various interpretations have been proposed, no definitive solution to the problem has been found. One of the most straightforward and effective approaches to this puzzle is an investigation of the magnetic moment distribution in addition to the charge distribution. In the muonic hydrogen hyperfine splitting (HFS), there is a contribution from a finite volume effect of the proton. This contribution is described by the Zemach radius, which is defined as a convolution of the charge distribution with the magnetic moment distribution. In order to shed some light on the puzzle, we proposed a first direct measurement of the muonic hydrogen ground-state HFS for a determination of the proton Zemach radius in the highest precision. The goal of the experiment is a measurement of the muonic hydrogen HFS with 1 ppm of relative uncertainty and a determination of the proton Zemach radius with 1% of precision. We utilize a high-intensity pulsed muon beam, an intense mid-infrared laser, a nuclear spin polarized hydrogen target, and a segmented electron detector. In this presentation, an experimental overview and development progress in each sub-system are discussed.

        Sterile neutrino searches at future colliders 30m
        Sterile neutrinos are attractive extensions of the Standard Model of particle physics to generate the light neutrino masses observed in neutrino oscillation experiments. When the sterile neutrinos are subject to a protective symmetry, they can have masses around the electroweak scale and potentially large neutrino Yukawa couplings, which makes them testable at possible future particle colliders. We discuss the production and decay channels at electron-positron, proton-proton and electron-proton colliders and highlight promising signatures for sterile neutrino searches.

        Fully differential NLO predictions for rare and radiative lepton decays 20m
        We present a general purpose Monte Carlo program for the calculation of the radiative ($\mu\to\nu\bar\nu e+\gamma$) and rare ($\mu\to\nu\bar\nu e+e^+e^-$) muon decays at NLO in the effective Fermi theory. These processes are irreducible Standard Model backgrounds to searches for lepton flavour violation at the PSI experiments MEG and Mu3e as they become indistinguishable from the corresponding signals when the neutrinos carry little energy. Furthermore, we argue that fully differential NLO corrections are very important for the analysis of measurements aiming at the percent level or better. This is especally true of very stringent phase-space cuts are applied. To illustrate this, we use a recent tension between BaBar's recent measurement of the radiative tau decay and the Standard Model prediction as an example of such an analysis.

        A proposal of a New Charged Lepton Flavor Violation Experiment: μ− e− → e− e− in muonic atom 20m
        We propose a new process of μ− e− → e− e− in a muonic atom for a quest of charged lepton flavor violation. The Coulomb attraction from the nucleus in a heavy muonic atom leads to significant enhancement in its rate, compared to μ+ e− → e+ e−. The search for this process could serve complementarily with the other relevant processes to shed light upon the nature of charged lepton flavor violation. The wave functions of bound and scattering state leptons are properly treated by solving Dirac equations with Coulomb interaction of the finite nuclear charge distributions. This new effect contributes significantly in particular for heavier atoms, where the obtained decay rate is about one order of magnitude larger than the previous estimation for 208 Pb in particular for contact interactions. We also discuss how to observe the differences among interaction types. It is based on the works arXiv:1003.1578(PRL 105(2010) 121601), arXiv:1603.01522 (PRD93 (2016) no.7, 076006) and work in progress.

The first part focuses on the three-flavor neutrino oscillation analysis with and without external constraints, optimized for sensitivity to the neutrino mass hierarchy, including data from all four run periods of the experiment. Confidence intervals for the oscillation parameters deltaM_23^2, sin^2_23, sin^2_13 and dCP are given for both normal and inverted hierarchy hypotheses. The combined result shows a slight preference for normal hierarchy. The second part presents the most recent results of the neutrino tau appearance analysis. The no-tau appearance hypothesis is excluded at 4.6sigma level, and the inclusive charged-current nu_tau cross-section is measured to be (0.94 ± 0.20) * 10^-38 cm^2

This talk will present IceCube's analysis of the tau neutrino appearance rate using roughly three years of livetime. Such a measurement adds to the precision of existing tau neutrino appearance measurements by Super-K and OPERA, deepening our understanding of the tau sector of the PMNS matrix.

        Measuring the Neutrino Mass Ordering and other oscillation parameters with KM3NeT-ORCA 27m
        ORCA (Oscillations Research with Cosmics in the Abyss) is the low-energy branch of KM3NeT, the next generation underwater Cherenkov neutrino detector in the Mediterranean. Its primary goal is to resolve the long-standing unsolved question of whether the neutrino mass ordering is normal or inverted by measuring matter oscillation effects with atmospheric neutrinos. The ORCA design foresees a dense configuration of KM3NeT detection units, optimised for studying the interactions of neutrinos in seawater at low (< 100 GeV) energies. To be deployed at the French KM3NeT site, at 2500 m depth ~40 km offshore Toulon, ORCA's multi-PMT optical modules will exploit the excellent optical properties of deep seawater to accurately reconstruct both cascade (mostly electron neutrinos) and track events (mostly muon neutrinos) with a few GeV of energy. The construction of the first detection units is proceeding. In this contribution we will report on the construction plan and will discuss the potentiality of the ORCA detector both in neutrino mass hierarchy studies and in obtaining new constraints on other key oscillation parameters.

        Charged-current quasi-elastic scattering at MINERvA 22m
        Charged-current quasi-elastic scattering is a particularly interesting interaction to understand. Not only is it a key signal process for oscillation experiments, but its relatively clean signature makes it an ideal channel to study multi-nucleon effects in the target nucleus. Over the past few years, Fermilab's MINERvA experiment has produced several studies of quasi-elastic scattering using the low-energy NuMI beam, which peaks in the 3GeV region. I will present a selection of results for both neutrino and antineutrino scattering on scintillator, including the world's first double-differential cross sections in this energy range, explaining what these can tell us about nuclear effects. In addition I will show a new result which demonstrates how the quasi-elastic cross section changes when scattering from different nuclei.

        Measurement of gamma-rays from neutron-oxygen reaction for neutrino-nucleus interaction 22m
        Precise knowledge of the neutrino neutral current quasielastic interaction cross section is important for several physics searches at Super-Kamiokande. For example, it is necessary to understand the background accurately in searches for supernova relic neutrinos and dark matter. At the T2K experiment the cross section has been measured but systematic errors are large. This is because neutrino interactions often produce nucleons whose subsequent gamma-ray production on oxygen is currently not well understood. Super-K and T2K must rely on models based on little data. In order to improve these models, measurements of gamma-ray production with a quasi-mono energetic neutron beam and water target have started at Osaka University’s Research Center for Nuclear Physics. Gamma-ray measurements were made with a germanium detector and a LaBr3(Ce) scintillator. In addition, the neutron flux was measured in order to estimate the gamma-ray production cross section. So far three experiments have been carried out with 80 MeV and 392 MeV (kinetic energy) neutrons, and 6.13 MeV gamma-rays were observed that are not currently modeled well in Super-K simulations. In this talk, these measurements and gamma-ray production cross section results will be presented.

        Sven-Patrik Hallsjö for the CERN NP05 Baby MIND collaboration (CERN, Geneva, Glasgow, INR Moscow, Sofia, Valencia) Abstract content The WAGASCI experiment being built at the J-PARC neutrino beam line will measure the difference in cross sections from neutrinos interacting with a water and scintillator targets, in order to constrain neutrino cross sections, essential for the T2K neutrino oscillation measurements. A prototype Magnetised Iron Neutrino Detector (MIND), called Baby MIND, has been constructed at CERN and will act as a magnetic spectrometer behind the main WAGASCI target. Baby MIND will be installed inside the WAGASCI cavern at J-PARC in the Autumn of 2017. Baby MIND will be able to measure the charge and momentum of the outgoing muon from neutrino charged current interactions, to enable full neutrino event reconstruction in WAGASCI. During the summer of 2017 Baby MIND was operated and characterised at the T9 test beam at CERN. Results from this test beam will be presented, including charge identification performance and momentum resolution for charged tracks. These results will be compared to the Monte Carlo simulations. Finally, simulations of charge-current quasi-elastic (CCQE) neutrino interactions in an active scintillator neutrino target, followed by the Baby MIND spectrometer, will be shown to demonstrate the capability of this detector set-up to perform cross-section measurements under different assumptions.

        Neutrino-nucleus scattering at nuSTORM 23m
        The nuSTORM facility will provide $\nu_e$ and $\nu_\mu$ beams from the decay of low energy muons confined within a storage ring. The instrumentation of the ring, combined with the excellent knowledge of muon decay, will make it possible to determine the neutrino flux at the \%-level or better. The neutrino and anti-neutrino event rates are such that the nuSTORM facility serving a suite of near detectors will be able to measure \nu_eN and \nu_\muN cross sections with the %-level precision required to allow the next generation of long-baseline neutrino-oscillation experiments to fulfil their potential. By delivering precise cross section measurements with a pure weak probe nuSTORM may have the potential to make measurements important to understanding the physics of nucleii. The precise knowledge of the initial neutrino flux also makes it possible to deliver uniquely sensitive sterile-neutrino searches. The concept for the nuSTORM facility will be presented together with an evaluation of its performance. The status of the planned consideration of nuSTORM at CERN in the context of the Physics Beyond Colliders workshop will be summarised. The possibility that nuSTORM could be implemented at the ESS will also be discussed.

        The high-intensity muon beam line (HiMB) project at PSI 22m
        Muons are an excellent tool for answering both fundamental and applied questions concerning the structure and properties of matter and consequently are in high demand at accelerator facilities. For the materials sciences, muon spin resonance techniques (muSR) are used to probe the magnetic structures of novel materials. In particle physics a number of fundamental measurements rely on the availability of large numbers of muons such as those of the searches for lepton flavour violating decays, the precise measurements of the muon decay properties and studies of muonic atoms. At the Paul Scherrer Institut (PSI) muon rates of up to 4x10^8 mu/s are available, produced by its 1.4 MW proton accelerator complex HIPA. While these are currently the highest muon rates available worldwide, projects in the US and Japan are underway that will be able to surpass these intensities by several orders of magnitude. In order to maintain PSI’s position at the intensity frontier in muon physics and to utilize the unique DC machine structure, a project has started to assess the possibility of creating a next-generation muon beam by modifying the existing Target M station. Initial studies showed that with a slanted slab target design viewed by two, closely placed normal-conducting solenoids as well as a solenoid based channel, surface muon rates of the order of 10^10 mu+/s can be achieved. This contribution will present these studies and the current status of the project.

        muCool: A novel high-brightness low-energy muon beam 23m
        The next generation experiments with muons and muonium atoms require high-intensity muon beams with low energy, small transverse size and small divergence. At the Paul Scherrer Institute, we are developing a novel device that reduces the phase space of a standard $\mu^{+}$ beam by a factor of $10^{10}$ with $10^{-3}$ efficiency. The phase space compression is achieved by stopping $\mu^{+}$ in cryogenic helium gas and applying strong electric and magnetic fields and gas density gradients. This device consists of several consecutive stages, which have been tested separately. The measurements show that we can achieve efficient muon beam compression, as predicted by the simulations. As a next step, we will combine the various stages and extract the compressed muon beam from the gas into vacuum. *This work is supported by SNF grant 200020_172639.*
