CP violation in beta decay from leptoquarks

Adam Falkowski (IJCLab, France)

CP-violating observables are one of the most formidable probes of physics beyond the Standard Model, which are often sensitive to new hypothetical particles beyond the reach of the present colliders. In this talk I will focus on CP violation in beta decay. I will first discuss this topic from the model-independent effective theory perspectives, which offers valuable lessons for building realistic models. Then I will present a comprehensive survey of leptoquark models that could lead to observable contributions to the D-parameter. Complementarity of various low- and high-energy experiments (beta decay, electric dipole moments, g-2, LHC) will be highlighted.
