Jet projects
1. inclusion of jet production in MC@NLO
Steve
Ellis,Bill Kilgore, Stefano Frixione, Joey Huston
2. jet algorithms at the Tevatron and LHC
-impact of negative towers: to remove or not to
remove, the D0 experience
-impact of splitting/merging
-understanding the effects of
splitting/merging at the parton and hadron level
-impact on boosted systems, e.g.
W->jj in high pT top
-understanding differences observed in jet
reconstruction between CDF and D0 environments
-reconstruct sample of
MC events that produce problems in the CDF environment
-utility of new algorithms such as JEF for final
state reconstruction
