Flavor Violation in Supersymmetric Q_6 Model

Understand

We investigate flavor violation mediated by Higgs bosons and supersymmetric particles in a predictive class of models based on the non-Abelian flavor symmetry Q_6.

• These models, which aim to reduce the number of parameters of the fermion sector and to solve the flavor changing problems of generic SUSY setup, assume three families of Higgs bosons and spontaneous/soft violation of CP symmetry.
• Tree-level contributions to meson-antimeson mixings mediated by Higgs bosons are shown to be within experimental limits for Higgs masses in the (1-5) TeV range.
• Calculable flavor violation induced by SUSY loops are analyzed for meson mixing and lepton decays and found to be consistent with data.
