Inclusive dijet events for pT>50 GeV. (PhaseSpace:pTHatMin=50 GeV). 20,000 events per file. PDF: LHAPDF6:NNPDF23_lo_as_0130_qed. The sample was created using the Pythia8 tune Tune:pp = 14, similar to ATLAS.

How to use

This is weighted events to obtain good statistics up to very large pT. This feature is set via PhaseSpace:bias2Selection and PhaseSpace:bias2SelectionPow = 5.0 (thanks to Caterina Doglioni). Use event weights to obtain correct pT distribution.

Slimmed as

Particle records are slimmed (all stable with pT>0.3 GeV) and (PID=5 || PID=6) or PID>22 && PID<38) or PID>10 && PID<17).
