This sample is for testing the ProIO file format. Please do not use it for physics. This sample corresponds to a small fraction of tev13pp_qcd_pythia8_weighted sample.

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.

How it was created

It uses the mc.proto model (attached to the file). Particle records use "VarintParticlesPacked" records. The mc.proto version is from Aug. 28, 2018.

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).
