Sherpa 2.0.β

Version 2.0.β is a pre-release of Sherpa. The main new feature compared to the 1.4.x series is the introduction of MEPS@NLO merging. Sherpa 2.0.β is not yet fit for production of event samples for arbitrary processes but rather intended to allow interested users to start exploring the new features.

The following processes have been validated so far

  • Jets (MENLOPS, MC@NLO, MEPS@LO)
  • ll+jets (MEPS@NLO, MENLOPS, MC@NLO, MEPS@LO)
  • lν+jets (MEPS@NLO, MENLOPS, MC@NLO, MEPS@LO)
  • h+jets in ggF (MEPS@NLO, MENLOPS, MC@NLO, MEPS@LO)
  • ttW (MC@NLO, MEPS@LO)

More processes will follow in the near future, and the code will be continously updated. The most recent version is always accessible through the svn repository.

If you spot any problem, please send us an email or post a ticket on trac. This will allow us to reach a mature version of the generator, suitable for physics analysis. If you would like to be informed about patches and newer releases, please subscribe to our announcement mailing list.
