Description
In the Standard Model (SM), charged Lepton Flavor Violation (cLFV) is highly suppressed to a negligible level by the finite but tiny neutrino masses. The BESIII experiment is a symmetric e+e- collider operating at c.m. energy from 2.0 to 4.95 GeV and has collected the world’s largest data set of J/psi (10 Billion), psi(2S) (2.7 Billion) on production threshold, and about 25 fb^-1 scan data from 3.77 to 4.95 GeV. This talk presents the cLFV searches at BESIII. The J/psi-> e tau/e mu is searched for with 10 Billion J/psi events and the result improves the previously published limit by two orders of magnitude.
