Charged lepton: results and future prospects
The flavor is not conserved in the quark and the neutrino sectors in the standard model of the particle physics. On the other hand, flavor violation is strictly forbidden in the charged lepton sector. Charged-lepton flavor violation (cLFV) is predicted in the most of new physics models. Searches of cLFV are powerful tools to discover an unambiguous evidence of the new physics. There is a wide variety of experiments searching for cLFV with using charged leptons. In this paper, the latest search results and prospects for the future are discussed.
