  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 $Z'$ boson. For the neutral scalar,
doubly charged scalar and $Z'$ 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.
