Description
In this talk, I will review recent ideas on how to discover axions and axion-like particles (ALPs) at present and future muon facilities. ALPs with flavour-conserving and flavour-violating couplings with the Standard Model (SM) leptons are a generic consequence of a broad class of new physics models featuring spontaneously-broken global U(1) symmetries. The talk will focus on the potential of the upcoming generation of low-energy/high-intensity muon experiments (targeting lepton-flavour-violating processes, such as MEGII, Mu3e, COMET, Mu2e) in detecting the decay of muons into electrons and invisible axions/ALPs. I will also briefly discuss the capability of the proposed high-energy muon colliders of testing ALP couplings with muons.
