Description:
Top production in bins of PhaseSpace:mHatMin. Cross section depends on pT. Use the attached log files to find the cross sections.

How to decode name

Name: tev100_pythia8_ptPTMIN_PTMAX_NUMBER.promc
where PTMIN is min pT for PhaseSpace:ptHatMin,
PTMAX - PhaseSpace:pTHatMax*2,
NUMBER corresponds to the cluster production node. 2000 events in file, 50 files per bin. When you run, use "PTMIN-PTMAX" ranges. The actual cut on PhaseSpace:pTHatMax=2*TMAX to reduce fluctuations in the tails.

How to use

To get a sample with a given pT, use "glob" regular expressions (in Jython, Python etc). Example for the code: pT>100 should corresponds to "glob.glob(*pt100_*)"

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).
