Looking for ultra-rare Standard Model interactions to search for new physics
The Standard Model of Particle Physics has been incredibly successful at describing every fundamental particle interaction which we have measured over the last decades. Interactions which are either forbidden by the Standard Model, or extremely rare offer an opportunity to look for effects which result from new physics contributions not described by the Standard Model. The COMET experiment currently being constructed in Japan will search for the Charged Lepton Flavour Violating (CLFV) decay of muons to electrons. The Standard Model calculation for this decay predicts an extremely small rate while many Beyond Standard Model (BSM) physics contributions would potentially give much larger rates. I will give a brief overview of progress in looking for BSM physics and describe how the COMET experiment hopes to either measure or set new constraints on CLFV decays.
