Sumario:Lepton flavor is a conserved quantity in the standard model of particle physics. It does not follow from an underlying gauge symmetry however, and from neutrino oscillation we know of its violation in the neutral sector. Charged lepton flavor violation induced by neutrino oscillation is heavily suppressed by the small neutrino and heavy gauge boson masses making its discovery extremely unlikely. Extensions of the standard model are able to enhance the branching fractions of such decays to levels observable at the LHC. Here, three searches for lepton flavor violation with the CMS experiment are presented: the decay of the Higgs boson into a muon and a tau lepton, and the decay of heavy resonances as well as the Z boson into an electron and a muon.
