Charged Lepton Flavor Violation at the High-Energy Colliders: Neutrino Mass Relevant Particles

Abstract

We summarize the potential charged lepton flavor violation (LFV) from neutrino mass relevant models, for instance the seesaw mechanisms. In particular, we study, in a model-dependent way, the LFV signals at the high-energy hadron and lepton colliders originating from the beyond standard model (BSM) neutral scalar $H$, doubly charged scalar $H^{\pm \pm }$, heavy neutrino $N$, heavy $W_R$ boson, and the $Z^{\prime }$ boson. For the neutral scalar, doubly charged scalar and $Z^{\prime }$ boson, the LFV signals originate from the (effective) LFV couplings of these particles to the charged leptons, while for the heavy neutrino $N$ and $W_R$ boson, the LFV effects are from flavor mixing in the neutrino sector. We consider current limits on these BSM particles and estimate their prospects at future high-energy hadron and lepton colliders.
