We analyze the CP asymmetry in flavor-specific decays [Formula: see text] for the [Formula: see text] mixing in the extension of the minimal supersymmetric standard model where baryon and lepton numbers are local gauge symmetries (BLMSSM). Considering the constraint of a 125 GeV Higgs, the numerical results indicate that the theoretical prediction of [Formula: see text] agrees with the current experimental result. For certain parameter sets, the BLMSSM contributions can be sizeable in [Formula: see text] mixing and CP asymmetry in B decays, which may help understand questions in cosmology.

One loop mediated charged Higgs bosons decays H± → W±V, V = Z, γ are studied in the Minimal Supersymmetric Standard Model (MSSM) with and without CP violating phases. We evaluate the MSSM contributions to these processes taking into account B → Xsγ constraint as well as experimental constraints on the MSSM parameters. In the MSSM, we found that in the intermediate range of tan β ≲ 10 and for large At and large μ, where the lightest top squark becomes very light and hence non-decoupled, the branching ratio of H± → W±Z can be of the order 10−3 while the branching ratio of H± → W±γ is of the order 10−5. We found also that the CP violating phases of soft SUSY parameters can modify the branching ratio by about one order of magnitude. We also show that MSSM with CP violating phases lead to CP-violating asymmetry in the decays H+ → W+V and H− → W−V. Such CP asymmetry can be rather large and can reach 80% in some region of parameter space.
