Description
Summary:A bstract We consider the tentative indication of flavor-violating Higgs boson decay h → μτ recently reported in the CMS experiment within the framework of minimal flavor violation. Specifically, we adopt the standard model extended with the seesaw mechanism involving right-handed neutrinos plus effective dimension-six operators satisfying the minimal flavor violation principle in the lepton sector. We find that it is possible to accommodate the CMS h → μτ signal interpretation provided that the right-handed neutrinos couple to the Higgs boson in some nontrivial way. We take into account empirical constraints from other lepton-flavor-violating processes and discuss how future searches for the μ → e γ decay and μ → e conversion in nuclei may further probe the lepton-flavor-violating Higgs couplings.
