FlexibleSUSY 2.2.0

FlexibleSUSY provides Mathematica and C++ code to create fast and modular spectrum generators for supersymmetric and non-supersymmetric models. It is based on SARAH and uses components from SOFTSUSY.

Quick start

If SARAH is not installed, please run


To create a spectrum generator for the NMSSM, execute the following commands:

./createmodel --name=NMSSM ./configure --with-models=NMSSM make

To run the NMSSM spectrum generator with an SLHA input file, run in the shell

./models/NMSSM/run_NMSSM.x --slha-input-file=model_files/NMSSM/LesHouches.in.NMSSM

Alternatively, the Mathematica interface of FlexibleSUSY may be used:

math -run "<< \"models/NMSSM/run_NMSSM.m""
