Ttbar plus jets study

From Wiki Les Houches 09

The idea is to perform a systematic study and comparison of the ttbar plus jets process, using the available codes, in particular

• ttbar+jet NLO (Dittmaier, Uwer, Weinzierl)
• MC@NLO
• POWHEG
• ALPGEN
• MADGRAPH
• PYTHIA

We plan to systematically compare the codes using relevant distributions, understand and learn from observed differences.

Interested people so far: Joanna Weng, Frank-Peter Schilling, Peter Uwer, Roberto Chierici and Stephen Mrenna
