Lepton-flavor violating axions at MEG II

High Energy Physics - Phenomenology 2022-10-26 v1

Abstract

We study the sensitivity of the existing MEG data to lepton flavor violating axion-like particles produced through μ+e+aγ\mu^+ \to e^+ a \gamma and estimate the discovery potential for the upcoming MEG II experiment in this channel. The MEG II signal efficiency can be improved significantly if a new trigger can be implemented in a dedicated run with a reduced beam intensity. This search would establish the world leading measurement in this channel with only 1 month of data taking.
