SuperIso Relic v3.0: A program for calculating relic density and flavour physics observables: Extension to NMSSM

Abstract

SuperIso Relic v3.0 is a public program for evaluation of relic density and flavour physics observables in the minimal supersymmetric extension of the Standard Model (MSSM) and next-to-minimal extension of the Standard Model (NMSSM). SuperIso Relic is an extension of the SuperIso program which adds to the flavour observables of SuperIso the computation of all possible annihilation and coannihilation processes of the LSP which are required for the relic density calculation. All amplitudes have been generated at the tree level with FeynArts/FormCalc, and widths of the Higgs bosons are computed with FeynHiggs or Hdecay at the two-loop level. SuperIso Relic also provides the possibility to modify the assumptions of the cosmological model, and to study their consequences on the relic density.

Phys. Comm. 181 (2010) 1277Does the new version supersede the previous version?: YesNature of problem: Calculation of the lightest supersymmetric particle relic density, as well as flavour physics observables, in the MSSM and NMSSM, in order to derive constraints on the supersymmetric parameter space.Solution method:SuperIso Relic uses a SUSY Les Houches Accord file, which can be either generated automatically via a call to SOFTSUSY, ISAJET, SPheno, SuSpect or NMSSMTools, or provided by the user. This file contains the masses and couplings of the supersymmetric particles. SuperIso Relic then computes the lightest supersymmetric particle relic density as well as the most constraining flavour physics observables. To do so, it calculates first the widths of the Higgs bosons with FeynHiggs or Hdecay, and then it evaluates the squared amplitudes of the diagrams needed for the relic density calculation. These thousands of diagrams have been previously generated with the FeynArts/FormCalc package. SuperIso Relic is able to perform the calculations automatically in different supersymmetric scenarios, such as CMSSM, NUHM, AMSB and GMSB, in the MSSM or NMSSM.Reasons for new version:SuperIso Relic has been extended to the next to minimal supersymmetric extension of the Standard Model (NMSSM).Summary of revisions:•Extension of the calculations to the NMSSM.•Addition of the “reheating” cosmological scenario.•Addition of a “configure” script for automated configuration.•Implementation of interfaces for SuSpect, SPheno, NMSSMTools, Hdecay and HiggsBounds.•Merging of the “shared” and “static” versions into a single version.•Addition of two different MSSM scenarios (HCAMSB and MMAMSB) and the NMSSM scenarios (CNMSSM, NGMSB and NNUHM).•Six sample main programs have been added: hcamsb.c, mmamsb.c, cnmssm.c, ngmsb.c, nnuhm.c and test reheating.c. Additional instructions are given when run without arguments.•msugra.c renamed as cmssm.c.•Updated parameter values.•Faster “static” compilation.Unusual features:SuperIso Relic includes the possibility to alter the underlying cosmological model and to test the influence of the cosmological assumptions.Running time: Compilation: a couple of hours for the static compilation, a few minutes for the dynamical compilation. Run: about one second, or a few seconds if libraries need to be compiled on the fly.
