We study impacts on new physics search from the rare decayIn a certain class of new physics models, the extra contributions to FCNC processes can be parametrized by its ratio to the standard model (SM) contribution with the common CKM factors. The ratio R 1 has been used in the analysis of x d and K parameters. In the above class of models, the K + → π + νν decay amplitude can be parametrized by the ratio R 2 . Then the experimentally allowed region for new physics contributions can be given in terms of R 1 , R 2 and the CP violating phase δ of the CKM matrix. Constraints on R 1 and cos δ are obtained by taking account of current experimental data and theoretical uncertainties on B 0 -B 0 and K 0 -K 0 mixings. We study impacts of future improved measurements by using (R 1 , R 2 , cos δ) basis. We discuss contributions in the minimal supersymmetric SM and the two Higgs doublet model as examples.

Super flavorsymmetry with multiple Higgs doublets

The meaning of non-abelian super flavorsymmetry in the presence of Multiple Higgs Doublets is twofold: The first one is to order the Yukawa sector of the standard model, while generating the Cheng-Sher suppression of tree-level Flavor Changing Neutral Currents (FCNCs), and the second one is to soften the fine tuning problem in the scalar potential and at the same time to suppress FCNCs coming from the soft breaking of supersymmetry. If spontaneous CP violation is combined with non-abelian super flavorsymmetry the CP phases in the soft supersymmetry breaking sector can disappear. This feature of super flavorsymmetry is reviewed and elaborated in a supersymmetric model of flavor based on the finite group Q 6 . The predictions of the model in ferimion mass and mixing, and flavor and CP violation can be tested in future experiments.
