Flavor issues in the Higgs Sector

We discuss the conditions under which the flavor structure of SUSY model induces, either radiatively or through mixing, new flavor-violating interactions in the Higgs sector. The radiative flavor mediation mechanism is illustrated using the minimal SUSY extension of the SM (MSSM) with generic trilinear A-terms, and applied to evaluate the corrections to Lepton Flavor-Violating (LFV) and Flavor-Conserving (LFC) Higgs vertices. Flavor mediation through mixing is discussed within the context of an E6-inspired multi-Higgs model, supplemented with an Abelian flavor symmetry. Tevatron and LHC can probe the flavor structure of these models through the detection of the LFV Higgs mode h → τμ, while NLC can perform high-precision tests of the LFC mode h → τ+τ−.
