SOFTSUSY: by Ben Allanach


[download | manual 1 | 2 | documentation | previous releases | subversion | wiki | contact]
This code provides a SUSY spectrum in the MSSM including flavour violation and with or without R-parity consistent with input Standard Model fermion mass/mixings and electroweak/strong coupling data. If you want to know how it works, watch a video of seminar I gave at CERN for ATLAS experimenters on the calculation. It is written in C++ with an emphasis on easy generalisability. Full three-family couplings and renormalisation group equations are employed, as well as one-loop finite corrections a la Bagger, Matchev, Pierce and Zhang. It can be used in conjunction with other programs for many different particle physics calculations: see a SUSY tools review. See a graph of MSSM RGE evolution at SPS1a (feel free to use it).

SOFTSUSY has been used to generate points in the CMSSM that fit current indirect data: you can obtain such points with their properties at the KISMET page.

If you use SOFTSUSY to write a paper, please cite

B.C. Allanach, Comput. Phys. Commun. 143 (2002) 305-331, hep-ph/0104145,

which is the SOFTSUSY manual for the R-parity conserving MSSM. If you use the R-parity violating aspects, please cite

Versions of manuals on the electronic arXiv will be updated with more recent editions.

There are detailed comparisons between SOFTSUSY and other publicly available codes in

Installation

To run SOFTSUSY, you should only need standard C++ libraries.

The following releases contain a test program (main.cpp) and the code for the SOFTSUSY library (libsoft.a, link with -L.libs -lsoft). There is also a Makefile: in linux, just unpack the files with (eg for softsusy-3.0)
> gunzip softsusy-3.0.tar.gz
> tar -xvf softsusy-3.0.tar
> cd softsusy-3.0
then type
> ./configure
> make
There are three C++ test programs, which can be run by the commands
> ./softpoint.x
> ./softsusy.x
> ./rpvsoftsusy.x

Release 3.0.8 18/06/09

NB If you want to do quark mixing in the R-parity conserving MSSM, either use SLHA2 or the new object FlavourMssmSoftsusy.
