Lepton flavor violating Higgs decays in a minimal doublet left-right symmetric model with an inverse seesaw

Abstract In this work, we study lepton flavor violation (LFV) decays within the framework of the Doublet Left-Right Symmetric model (DLRSM). The model features an extended gauge and scalar sector, including a bidoublet and two doublets that induce new charged current interactions. Spontaneous Symmetry Breaking (SSB) occurs in two stages, introducing a new scale associated with the vacuum expectation value (VEV) of the right-handed doublet which is assumed to lie above the electroweak scale. Neutrino masses are generated via the inverse seesaw (ISS) mechanism, allowing sizable mixing between active and sterile neutrinos. We diagonalize the full neutrino mass matrix and express the mixing in terms of physical parameters. We compute the branching ratios for LFV radiative and Higgs decays as functions of the heavy neutrino mass. Our numerical analysis incorporates current experimental bounds and projected sensitivities, highlighting viable regions of parameter space where LFV signals could be probed at future colliders.
