NLO and NNLL for ttbar production

Asked by Sean Wu

Hi,
I'm trying to produce ttbar background for a study and I would like to include NLO and NNLL. Is there a command that I can use to do this at the generation level?
Thanks

Sean

Hi,
what you can do is to generate events with NLO accuracy to be eventually showered
by an MC such as Herwig or Pythia. The latter have a formal LL accuracy, although
it is known that they actually do better than that in practice.
The command is generate p p > t t~ [QCD], ie the same as at the LO except
for [QCD]. There is an online tutorial for aMC@NLO operations -- see
also amcatnlo.cern.ch.
Regards, Stefano.
