SuperIso: A program for calculating the isospin asymmetry of image in the MSSM Original Research Article

We present a program for calculating the isospin symmetry breaking in image decays in the MSSM with minimal flavor violation. This program calculates the NLO supersymmetric contributions to the isospin asymmetry, using the effective Hamiltonian approach and within the QCD factorization method. We show that isospin symmetry breaking proves to be a very restrictive observable, in particular in the mSUGRA parameter space. The program also calculates the inclusive branching ratio associated to image transition, as a comparison reference.
