Lepton Flavor Violating Higgs Decays in a Minimal Doublet Left-Right Symmetric Model with an Inverse Seesaw (2508.01220v1)

Abstract: In this work , we study the Lepton Flavor Violation (LFV) of Higgs decays in the context of the Doublet Left-Right Symmetric model (DLRSM), based on the gauge group $SU\left(2\right){L}\otimes SU\left(2\right){R}\otimes U\left(1\right){B-L}$. The enlarged gauge and Higgs sectors induce new charged currents interactions. Spontaneous symmetry breaking occurs in two stages, with a new scale arising from the vacuum expectation value $v{R}$ of the right-handed doublet. We consider scenarios where $v_{R}$ is above the electroweak scale. Neutrino masses are generated via the inverse seesaw mechanism, leading to LFV through neutrino mixing. We diagonalize the full neutrino mass matrix and express the mixing in terms of physical parameters. We also explore the scalar sector to reproduce the observed Higgs mass and compute LFV Higgs decays rates as functions of the heavy neutrino scale.
