Description
We study lepton flavor violating Higgs decays in the light of the recent enhancement in the τμ channel, which should be confirmed/excluded soon at the second run of the LHC. In the first part of the talk, I will discuss tree-level and loop-level realizations that can accommodate the excess starting from an EFT analysis, while being at the same time compatible with other low-energy constraints. From our study, we can extract robust upper bounds to the maximum allowed value on H->τμ for the different topologies. In the second part, I will discuss neutrino mass models and their lepton flavor violating decays, finding that loop-level realizations are always too suppressed, while a 2HDM can explain the enhancement. Finally, we will discuss two well-motivated scenarios: left-right symmetric models and the Zee model, for which a detailed numerical analysis is currently being performed.
