SuperIso v3.0, flavor physics observables calculations: extension to NMSSM

Abstract

SuperIso v3.0 is a public program for evaluation of flavor physics observables in the minimal supersymmetric extension of the Standard Model (MSSM) and the next to minimal supersymmetric extension of the Standard Model (NMSSM). SuperIso v3.0 incorporates many flavor observables such as the inclusive branching ratio of B → X s γ , the isospin asymmetry of B → K ∗ γ , the branching ratio of B s → μ + μ − , the branching ratio of B → τ ν τ , the branching ratio of B → D τ ν τ , the branching ratio of K → μ ν μ and the branching ratios of D s → τ ν τ and D s → μ ν μ . The calculation of the branching ratio of B → X s γ includes NNLO Standard Model contributions. The program also computes the muon anomalous magnetic moment ( g − 2 ) . Seven sample models are included in the package, namely mSUGRA, NUHM, AMSB and GMSB for the MSSM, and CNMSSM, NGMSB and NNUHM for the NMSSM. 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 (SOFTSUSY, ISAJET or NMSSMTools), or provided by the user.

Solution method: SuperIso uses a SUSY Les Houches Accord (SLHA1 or SLHA2) file, which can be either generated automatically via a call to SOFTSUSY, ISAJET or NMSSMTools, or provided by the user. This file contains the masses, mixings and couplings of the supersymmetric particles. SuperIso then computes the most constraining flavor physics observables and the muon ( g − 2 ). SuperIso is able to perform the calculations in different supersymmetry breaking scenarios, such as mSUGRA, NUHM, AMSB and GMSB, as well as constrained NMSSM scenarios such as CNMSSM, NNUHM and NGMSB. Reasons for new version: SuperIso has been extended to the next to minimal supersymmetric extension of the Standard Model (NMSSM). The implemented routines are therefore extensively modified. Summary of revisions: • Improvement of the SLHA2 reader. • Replacement of “float” variables by “double”. • Implementation of an interface with NMSSMTools. • Extension of the calculation of flavor observables as well as the muon anomalous magnetic moment to NMSSM. • Addition of three different NMSSM scenarios: CNMSSM, NGMSB and NNUHM. • Three sample main programs have been added: cnmssm.c, ngmsb.c and nnuhm.c. Additional instructions to use them are given when running them without arguments. Unusual features: The code is very flexible, and new observables can be added easily. Running time: Less than 1 sec
