SuperIso v2.3: A program for calculating flavor physics observables in supersymmetry Original Research Article

We describe SuperIso v2.3 which is a public program for evaluation of flavor physics observables in the minimal supersymmetric extension of the Standard Model (MSSM). SuperIso v2.3, in addition to the isospin asymmetry of image, which was the main purpose of the first version, incorporates new flavor observables such as the branching ratio of image, the branching ratio of image, the branching ratio of image and the branching ratio of image. The calculation of the branching ratio of image is also improved in this version, as it now includes NNLO Standard Model contributions in addition to partial NLO supersymmetric contributions. The program also computes the muon anomalous magnetic moment image. Four sample models are included in the package, namely mSUGRA, NUHM, AMSB and GMSB. SuperIso uses a SUSY Les Houches Accord file (SLHA1 or SLHA2) as input, which can be either generated automatically by the program via a call to external spectrum calculators, or provided by the user. The calculation of the observables is detailed in the Appendices, where a suggestion for the allowed intervals for each observable is also provided.
