${\mu }^{-}\to e^{-}\gamma$ in a muonic atom as a probe for effective lepton flavor violating operators involving photon fields

Yuichi Uesaka, Masato Yamanaka, Yoshitaka Kuno

We propose the ${\mu }^{-}\to e^{-}\gamma$ process in a muonic atom as a novel means to investigate charged lepton flavor violation (CLFV). We demonstrate its sensitivity in probing effective CL…
