CP-violating axions

Jul 26, 2021, 11:05 AM


Parallel session talk Flavour Physics and CP Violation T08: Flavour Physics and CP Violation


Luca Di Luzio (University of Padua and INFN)


While the axion was originally introduced to "wash out" CP violation from strong interactions, new sources of CP violation beyond QCD (needed e.g. for the matter-antimatter asymmetry) might manifest themselves via a tiny scalar axion-nucleon component. The latter can be experimentally probed in axion-mediated force experiments, as suggested long ago by J.E. Moody and F. Wilczek. In the present contribution, I will review CP-violating axion searches and report on a recent calculation of the scalar axion-nucleon coupling based on chiral Lagrangian techniques.
