Abstract

We present SUSY\_FLAVOR version 2 - a Fortran 77 program that calculates low-energy flavour 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 (-&gt; e\gamma, -&gt; \mu\gamma, e\gamma). 4. Rare Kaon decays (K^0\_L -&gt; \pi^0 \nu\nu, K^+ -&gt; \pi^+ \nu\nu). 5. Leptonic B decays (B\_q -&gt; l^+ l^-, B -&gt; \nu, B -&gt; D \nu). 6. Radiative B decays (B -&gt; X\_s \gamma). 7. \Delta F=2 processes (K^0--K^0, D--D, B\_d-B\_d and B\_s-B\_s 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(\beta) and/or large trilinear soft mixing terms to all orders in perturbation theory. Also, in SUSY\_FLAVOR v2 new routines calculating of B -&gt; (D) \nu, g-2, radiative lepton decays and Br(l -&gt; l'\gamma) were added. All calculations are done using exact diagonalization of the sfermion mass matrices. The program can be obtained from <a href="http://www.fuw.edu.pl/susy\_flavor.">this http URL</a>
