Comments:
- Exact LO matrix elements for 2->n
multiparton processes at hadron colliders
- Especially suited for boson(s)+jets (including
heavy flavour) and ttbar productions
- Produces weighted and unweighted events
- Programming Language: Fortran 77 and 90
- Interfaced with Pythia or Herwig for events
generation in D0
- Herwig interface also exists, both Pythia and
Herwig interfaces are "Les Houches Accord" compliant
- Correct handling of parton flavour, color and
polarization
- Current D0 version: 2.05 (Fall 2005)
Known Bugs and Caveats:
- Wc (single c-quark)
production. Fixed in p17.09.07.
