# Charged LFV searching in J/psi decays at BESIII

## Speakers

• Mengzhen WANG

## Abstract

The charged Lepton Flavor Violation (cLFV) is highly suppressed in the Standard Model (SM) by the finite but tiny neutrino masses. Its branching fraction is calculated to be at a negligible level and so far none has been found in all the historical experiments, including searches in lepton ($\mu$,$\tau$) decays, pseudoscalar meson (K,$\pi$) decays, vector meson ($\phi$,$J/\psi$,$\Upsilon$) decays, Higgs decays etc.
