Description:
Inclusive dijet events for pT>50 GeV. (PhaseSpace:pTHatMin=50 GeV). PDF: LHAPDF6:NNPDF23_lo_as_0130_qed. Pythia8 tune Tune:pp = 14 similar to ATLAS. Created for studies by Frank Taylor.

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. 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).
