Parsing, manipulating, and visualising SUSY Les Houches Accord data

Project description

A simple but flexible parser of SUSY Les Houches Accord (SLHA) model and decay files.

pyslha is a parser/writer module for particle physics SUSY Les Houches Accord (SLHA) supersymmetric spectrum/decay files, and a collection of scripts which use the interface, e.g. for conversion to and from the legacy ISAWIG format, or to plot the mass spectrum and decay chains.

The current release supports SLHA version 1. Assistance with supporting version 2 will be gladly accepted!

The plotting script currently provides output in a source form usable by the Rivet make-plots system, but alternative formats are in the pipeline. Again, contributions or suggestions of new formats are very welcome.

TODOs:
  • Identify HERWIG decay matrix element to use in ISAWIG

  • Order decay products as required by HERWIG in ISAWIG

  • What to do about unlisted PIDs?

  • Split writeSLHA into writeSLHA{Blocks,Decays}

  • Handle SLHA2

  • Handle RPV SUSY in ISAWIG
