Abstract

We present SUSY_FLAVOR version 2.5 - program that calculates over 30 low-energy flavor observables in the general $R$-parity conserving MSSM. Comparing to previous versions, in SUSY_FLAVOR v2.5 parameter initialization in SLHA2 formats has been significantly generalized, so that the program accepts most of the output files produced by other libraries analyzing the MSSM phenomenology. Number of bugs and inconsistencies have been fixed, based on users feedback. Calculations of several processes implemented in earlier versions have been corrected. New processes of rare decays of the top quark to Higgs boson have been included. Variables controlling inclusion of contributions from various MSSM sectors have been added. Full updated manual of SUSY_FLAVOR v2.5 integrating the details of the modifications listed below can be found at {\tt arxiv.org/abs/arXiv:1203.5023}.
