| - | The idea is to compare the latest version of all generators to be able to see what the current status of the predictions is. So far, this has never been done for top pair production, including multi-jet merging. The set-up is the following: | ||
| - | |||
| - | *13 TeV. | ||
| - | *di-lepton top decays. | ||
| - | *Including hadronisation, but no underlying event or MPI. | ||
| - | *Use MC truth for top reconstruction, i.e., the lepton, neutrino and b-jet momentum. | ||
| - | |||
| - | Interesting observables are: | ||
| - | *Gap fraction, excluding the b-jets from the top decay | ||
| - | *top pT spectrum | ||
| - | *jet multiplicity, both with 30 and 50 GeV jet cuts | ||
| - | *jet pT's for the 3 hardest jets | ||
| - | *transverse momentum of the top pair system | ||
| - | *reconstructed mass of the top quark | ||
| - | *asymmetry | ||
| - | *tt+jets as background to ttH. Input from the ttH Working Group here. | ||
