SDECAY - A Fortran Code for SUSY Particle Decays in the MSSM
  The Fortran code SDECAY calculates the decay widths and branching ratios of all supersymmetric (SUSY) particles in the Minimal Supersymmetric Standard Model (MSSM), including higher order effects. The usual two-body decays of sfermions and gauginos as well as the three-body decay modes of charginos, neutralinos and gluinos are included. Furthermore, the three-body stop and sbottom decays and even the four-body stop decays are calculated. The important loop-induced decays, the QCD corrections to the two-body widths involving strongly interacting particles and the dominant electroweak effects to all processes are evaluated as well.
