Precision Tests of the Standard Model [PrecisionSM (STRONG2020)]
Precision experiments at low energy, often called the Intensity Frontier of the Standard Model, entail measuring parameters of SM with high precision thereby constraining the contributions of yet unknown non-standard interactions and particles. While collider searches are best suited to look for heavy new particles, low-energy tests are sensitive to the full range of new physics. Some experimental programs that define the context of this proposal are: precise determination of the muon anomalous magnetic moment (g-2)μ; extraction of the CKM matrix element Vud from beta decay; the weak mixing angle from parity-violating electron scattering (PVES). The new physics reach of these tests of SM is directly related to their precision which consists of the proper accuracy of the experiment, and that of theoretical calculations of radiative corrections (RC). In all processes the precision requires accounting for the effects of the structure of hadrons in the kinematical regime where QCD is non-perturbative.
