# SOFTSUSY: A program for calculating supersymmetric spectra

## Description

Abstract SOFTSUSY is a program which accurately calculates the spectrum of superparticles in the Minimal Supersymmetric Standard Model (MSSM). The program solves the renormalisation group equations with theoretical constraints on soft supersymmetry breaking terms provided by the user. Weak-scale gauge coupling and fermion mass data (including one-loop finite MSSM corrections) are used as a boundary condition, as well as successful radiative electroweak symmetry breaking. The program can also calculate... Title of program: SOFTSUSY Catalogue Id: ADPM_v1_0 Nature of problem The determination of sparticle masses and couplings of SUSY particles in the R-parity conserving MSSM is the basic problem. Low energy data on Standard Model fermion masses, gauge couplings and electroweak boson masses are to be used as a constraint. SUSY radiative corrections from sparticle loops to these inputs depend upon the sparticle spectrum, and must be calculated. Theoretical constraints on the SUSY breaking parameters from a higher theory are often imposed at a high renormalisation scal ...
