  Charged lepton flavor violation has long been recognized as unambiguous
signature of New Physics. Here we describe the physics capabilities and
discovery potential of New Physics models with charged lepton flavor violation
in the tau sector as its experimental signature. Current experimental status
from the B-Factory experiments BaBar, Belle and Belle II, and future prospects
at Super Tau Charm Factory, LHC, EIC and FCC-ee experiments to discover New
Physics via charged lepton flavor violation in the tau sector are discussed in
detail.
