Open issues

  • Need to be more explicit about versions of generators required
  • Need to check what can be done with Pythia8
  • Whenever possible, do we compare cross-sections from different generators ?

A les houches BSM svn repository will be setup to store data cards (FeynRules or others) for the different points/generators. Please contact Renaud.BruneliereNoSpamcern.ch and Filip.MoortgatNoSpamcern.ch for getting writting rights.
