Distinguishing muon LFV effective couplings using $\mu+e^-\rightarrow e^-+e^-$

Abstract

A search for µ − e − → e − e − process in a muonic atom is one of the promising probe for charged lepton flavor violation (CLFV). In this work, we investigate an asymmetry of the emitted electrons when the initial muon bound by the nucleus is polarized.
