SUSY_FLAVOR: A computational tool for FCNC and CP-violating processes in the MSSM

We present SUSY_FLAVOR – a Fortran 77 program that calculates important leptonic and semi-leptonic low-energy observables in the general R  -parity conserving MSSM. For a set of input MSSM parameters, the code gives predictions for the K¯0K0, D¯D, B¯dBd and B¯sBs mixing parameters; B→XsγB→Xsγ, Bs,d→l+l−Bs,d→l+l−, KL0→π0ν¯ν and K+→π+ν¯ν decay branching ratios; and the electric dipole moments of the leptons and the neutron. All these quantities are calculated at one-loop level (with some higher-order QCD corrections included) in the exact sfermion mass eigenbasis, without resorting to mass insertion approximations.

The input parameters can be read from an external file in SLHA format.Restrictions: The results apply only to the case of MSSM with R-parity conservation.Running time: For single parameter set approximately 1 s in double precision on a PowerBook Mac G4.
