Phenomenology of CP Violation in a Flavor Blind MSSM and Beyond

We present an analysis of low energy CP violating observables in the Minimal Supersymmetric Standard Model (MSSM). We focus on the predictions of CP violation in b→s transitions in the framework of a flavor blind MSSM, where the CKM matrix remains the only source of flavor violation, but additional CP violating phases are introduced in the soft SUSY breaking sector. We find large and strongly correlated effects in ΔF = 0 observables like the electric dipole moments (EDMs) of the electron and the neutron, as well as in ΔF = 1 observables like the time dependent CP asymmetries in B→φ Ks and B→η' Ks, the direct CP asymmetry in b→sγ and in several CP asymmetries in B→K*μ+μ-. On the other hand, observables that are only sensitive to CP violation in ΔF 2 transitions, in particular the Bs mixing phase, are found to be SM like in this framework. We stress that only in presence of additional sources of flavor violation, sizeable New Physics effects to CP violation in meson mixing can occur.
