### Description

The charged lepton flavor violation (CLFV) is a good probe to search for new physics beyond the standard model. If there is a neutral boson X which is lighter than muon and has CLFV interaction, a muon can decay into an electron and an X, i.e. $\mu\to eX$. The search for this process is expected to constraint the property of X. In this talk, we focus on a search for the rare decay of muon in a muonic atom. We show general quantitative calculation for the electron spectrum.
