Searching for $$\tau \rightarrow \mu \gamma $$ τ → μ γ lepton-flavor-violating decay at super Charm-Tau factory
We investigate the possibility of searching the lepton-flavor-violating (LFV) $\tau\rightarrow \mu\gamma$ rare decay at the Super Charm-Tau Factory (CTF). By comparing the kinematic distributions of the LFV signal and the standard model (SM) background, we develop an optimized event selection criteria which can significantly reduce the background events. It is …
