SUSY_FLAVOR library and constraints on $B_s \to μ^+ μ^-$ decay rate

I present SUSY_FLAVOR - a Fortran 77 program able to calculate simultaneously 29 low-energy flavor and CP-violating observables in the general R-parity conserving MSSM, including the case of large flavor violation in the sfermion sector. SUSY_FLAVOR v2 performs also the resummation of chirally enhanced corrections, arising in large $\tanβ$ regime and/or large trilinear soft mixing terms, to all orders of perturbation theory. I discuss an example of application of SUSY_FLAVOR to analysis of the $B_s \to μ^+ μ^-$ decay rate in the MSSM.
