abstract

We study lepton flavor violation in a class of supersymmetric models with light sgoldstino - scalar superpartner of Goldstone fermions responsible for spontaneous supersymmetry breaking. Sgoldstino couplings to the Standard Model (SM) fermions are determined by the MSSM soft terms and, in general, provide with flavor violation in this sector. Sgoldstino admixture to the lightest Higgs boson results in changes of its coupling constants and, in particular, leads to lepton flavor-violating decay $h\to\tau\mu$ of the Higgs resonance. We discuss viability and phenomenological consequences of this scenario.

  1. Higgs lepton flavor violating decays in Two Higgs Doublet Models

    hep-ph 2019-08 conditional novelty 1.0 of 10

    A mini-review explaining that the type-III two Higgs doublet model can produce h to tau mu branching ratios near the present CMS bound while remaining compatible with tau to mu gamma and related flavor constraints.
