The axion is a hypothetical particle emerging from the Peccei-Quinn mechanism, which was proposed to solve the strong CP problem in quantum chromodynamics. With a mass below the electron-volt range, axions interact feebly with Standard Model particles, making them a strong candidate for dark matter. One of the most sensitive methods for dark matter axion detection is the cavity haloscope. This...
Sub-GeV dark matter (DM) has been gaining significant interest in recent years, since it can account for the thermal relic abundance while evading nuclear recoil direct detection constraints. However, sub-GeV DM is still subject to a number of constraints from laboratory experiments, and from astrophysical and cosmological observations. In this work, we compare these observations with the...
The present work addresses the puzzle related to the observation of collective flow in collisions of small systems and the apparently contradictory absence of jet quenching in those cases. This study has been done using the JEWEL event generator with a "brick"-like medium made up of a collection of gluons at a certain temperature and density in a given ellipsoidal region of space. This...
There exists an imbalance between matter and antimatter in the Universe. Charge parity violating (CP) mechanisms are necessary to generate such an asymmetry.
CP violation has only been observed in weak decays of mesons. Baryon weak decays offer unique and complementary ways of testing the validity of the Standard Model. Notably, spin polarization can significantly enhance the sensitivity of...
