Charge lepton flavor violation in the tau sector, an
unambiguous signature of New Physics, has been searched in many
channels by multiple collaborations, including BaBar, Belle, Belle II,
LHCb, ATLAS and CMS. Current experimental status and future
improvements are discussed. Combined upper limits as compiled by the
Tau subgroup of the Heavy Flavor Averaging group are presented, for
channels where multiple searches provide significant contributions.
Future discovery potential of several new physics models at Belle II,
HL-LHC, EIC, STCF and FCC
with charged lepton flavor violation as its experimental signature are
presented,
along with constraints on Wilson coefficients on different lepton
flavor violating operators in an effective field theory approach. |
