Abstract

The ATLAS and CMS collaborations reported the first signal of Lepton Flavor Violating (LFV) Higgs decay into τ and µ leptons. Standard Model forbids such processes at the renormalizable level because of lepton flavor symmetry. On the other hand, many extensions of the Standard Model do not exhibit such a symmetry and the models beyond the Standard Model (BSM) yield such processes. Hence, any signal for LFV processes can be interpreted as a direct probe for the BSM models. In this work, we consider LFV Higgs boson decays in a class of supersymmetric models including minimal supersymmetric extension of the SM (MSSM), Supersymmetric Type I Seesaw, and U(1)B−L extended MSSM supplied with the inverse seesaw mechanism for non-zero neutrino masses.
