Comparison of Monte Carlo generator predictions to ATLAS measurements of top pair production at 7 TeV

This note summarizes some of the latest Monte Carlo generator studies using ttbar events in ATLAS. Variations of the scale and h_damp parameters in the Powheg+Pythia6 setup are compared to ATLAS measurements of ttbar production. In addition, Powheg+Pythia8 and MadGraph5_aMC@NLO+Herwig++ are also com...

Sumario:This note summarizes some of the latest Monte Carlo generator studies using ttbar events in ATLAS. Variations of the scale and h_damp parameters in the Powheg+Pythia6 setup are compared to ATLAS measurements of ttbar production. In addition, Powheg+Pythia8 and MadGraph5_aMC@NLO+Herwig++ are also compared to the same measurements.
