Nature of problem:
Calculation of isospin asymmetry in BK*γ decays in the Minimal Supersymmetric extension of the Standard Model with minimal flavor violation. This observable brings severe constraints on the supersymmetric parameter space.

Solution method:
SuperIso uses a SUSY Les Houches Accord file, which can be either generated automatically by calling SOFTSUSY or ISAJET, or provided by the user. This file contains the masses and couplings of the supersymmetric particles. SuperIso then computes Wilson coefficients, which are used to calculate the isospin symmetry breaking in the BK*γ decays, as well as the inclusive branching ratio of BXsγ. SuperIso is able to perform the calculation in different supersymmetry breaking scenarios, such as mSUGRA, AMSB and GMSB.

This calculation is valid only in the MSSM with minimal flavor violation.

Unusual features:
The code is very modular, and new routines for calculating new physical observables such as the branching ratio of Bs → μ+μ-, can be easily added.

Additional comments:
The module which reads the SUSY Les Houches Accord file can be used independently in other programs.
