Top production at the tevatron
Top production at the Tevatron production

most complete treatment in

paper by Kuhn and Rodrigo

effect not present in LO MC’s

use MCFM to study at parton level


Properties of t tbar events
Properties of t-tbar events production

  • All MCFM plots will show the cross section in fb

  • MCFM final state consists of a t, a tbar and (maybe) 1 gluon

@NLO jet pT is ttbar pT


Asymmetry
Asymmetry production


Asymmetry1
Asymmetry production



P t j 10 gev c
p productionTj > 10 GeV/c



Scale dependence of asymmetry
Scale dependence of asymmetry production

…either puzzling or profound?


Next steps
Next steps production

  • More studies cross-checks with MCFM

    • t-tbar + 1 jet at NLO complete later this summer; useful for looking at high pT asymmetry

      • synergy with ttbar + jet study

    • I’ve been talking with the authors

  • Continue studies with MC@NLO samples

    • effects of soft gluon radiation on asymmetry

      • ability to tag hard/soft t-tbar production

    • feedback for optimizing analysis procedure/cuts on the data
