SuperIso Relic: A program for calculating relic density and flavor physics observables in Supersymmetry

We describe SuperIso Relic, a public program for evaluation of relic density and flavour physics observables in the minimal supersymmetric extension of the Standard Model (MSSM) and in the next-to-minimal supersymmetric 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 LanHEP/FeynArts/FormCalc, and widths of the Higgs bosons are computed with FeynHiggs or Hdecay at the twoloop level. SuperIso Relic also provides the possibility to modify the assumptions of the cosmological model, and to study their consequences on the relic density.
