Higgs lepton flavor violation
2015 (English)In: Proceedings of Science, Proceedings of Science (PoS) , 2015Conference paper (Refereed)
We study lepton-flavor-violating Higgs decays in the light of the recently observed deviation in the H → τμ channel with respect to the Standard Model, which should be confirmed/excluded in the second run of the LHC. Starting from an EFT approach, we discuss both tree-level and looplevel UV completions. In particular, we find that, in agreement with previous analyses, loop-level realizations are in general too suppressed, while models containing at least two Higgs doublets can explain the enhancement. We also analyze well-motivated neutrino mass models that could in principle accommodate the excess, finding two popular examples: the Zee model and left-right symmetric models. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
