SUSY_FLAVOR v2: A computational tool for FCNC and CP-violating processes in the MSSM

We present SUSY FLAVOR version 2 — a Fortran 77 program that calculates low-energy flavor observables in the general R-parity conserving MSSM. For a set of MSSM parameters as input, the code gives predictions for: 1. Electric dipole moments of the leptons and the neutron. 2. Anomalous magnetic moments (i.e. g − 2) of the leptons. 3. Radiative lepton decays (μ → eγ and τ → μγ, eγ). 4. Rare Kaon decays (K0 L → π0ν̄ν and K+ → π+ν̄ν). 5. Leptonic B decays (Bs,d → l+l−, B → τν and B → Dτν). 6. Radiative B decays (B → X̄sγ). 7. ∆F = 2 processes (K̄0–K0, D̄–D, B̄d–Bd and B̄s–Bs mixing). Comparing to SUSY FLAVOR v1, where the matching conditions were calculated strictly at one-loop level, SUSY FLAVOR v2 performs the resummation of all chirally enhanced corrections, i.e. takes into account the enhanced effects from tan β and/or large trilinear soft mixing terms to all orders in perturbation theory. Also, in SUSY FLAVOR v2 new routines calculating of B → (D)τν, g− 2, radiative lepton decays and Br(l → lγ) were added. All calculations are done using exact diagonalization of the sfermion mass matrices. The program can be obtained from http://www.fuw.edu.pl/susy flavor.
