General flavor blind minimal supersymmetric standard model andCPviolation

subject

description

We study the implications on flavor changing neutral current and $\mathrm{CP}$ violating processes in the context of supersymmetric theories without a new flavor structure (flavor blind supersymmetry). The low-energy parameters are determined by the running of the soft breaking terms from the grand unified scale with supersymmetric (SUSY) phases consistent with the electric dipole moment constraints. We find that the $\mathrm{CP}$ asymmetry in $\stackrel{\ensuremath{\rightarrow}}{b}s\ensuremath{\gamma}$ can reach large values potentially measurable at B factories, especially in the low $BR(\stackrel{\ensuremath{\rightarrow}}{b}s\ensuremath{\gamma})$ region, while the contributions to electric dipole moments are kept under control through a cancellation mechanism. We perform a fit of the unitarity triangle including all the relevant observables. In this case, no sizable deviations from the standard model expectations are found. Finally, we analyze the SUSY contributions to the anomalous magnetic moment of the muon pointing out its impact on the $\stackrel{\ensuremath{\rightarrow}}{b}s\ensuremath{\gamma}$ $\mathrm{CP}$ asymmetry and on the SUSY spectrum including chargino and top squark masses.
