Abstract

In SUSY models, it is still possible to have large signals even if the current data on K and B systems are consistent with the CKM paradigm for flavor mixing and CP violation. I first discuss b→ d and b→ s transitions including time-dependent CP asymmetries in B_d → ϕK_s, and usefulness of B_s → μ⁺ μ^- to distinguish various SUSY breaking mechanisms. Then I will discuss some possible connections between B physics and cosmology: (i) B physics and electroweak baryogenesis within SUSY models, and (ii) the correlation between the neutralino dark matter scattering and B (B_s → μ⁺ μ^-).
