Flavour phenomenology of axion-like particles

• Sophie Renner (SISSA)

Axion-like particles (ALPs) with mass below the electroweak scale are well motivated relics of high energy extensions of the Standard Model. In this talk I will give an overview of their phenomenology in quark- and lepton-flavour changing processes, and how they can be correlated with effects in other observables. I will explain how quark flavour measurements provide the best constraints in some important ALP parameter space regions, for GeV scale masses. I will also discuss lepton flavour violating ALPs, and how they could play a role in the measured deviations in the anomalous magnetic dipole moments of muons and electrons.
