Lepton flavor violating Higgs decays in models with massive neutrinos.

The decays $h\to\ell_a\ell_b$ with lepton flavor violation (LFV) represent new physics signals. We present a general framework for computing them at one loop in extensions of the Standard Model with neutrino masses, classifying all contributing diagrams according to their fermionic loop content and implementing the results in the public code \texttt{OneLoopLFVHD}. The framework is applied systematically to three BSM models: Seesaw tipo I, Seesaw Inverso y DLRSM+ISS. Only the DLRSM with Inverse Seesaw reaches current LHC sensitivity, yielding the bound $v_R < 2.7\times10^5$ GeV from $\mathrm{BR}(h\to\mu\tau)$, testable at the HL-LHC and at a future muon collider $\mu$C.
