Introduction

The following is a description of the inclusive jet + dijet cutflow. Although the cuts diverge after a certain point, please run the cut flow for both selection criteria.

Event/Jet Selection

The same used in the main JetCrossSection2011 twiki page. This includes using fully re-calibrated and pileup offset corrected jets:
  • Current tag: ApplyJetCalibration-00-01-02
  • Config file: CalibrationConfigs/InsituJES_2011_Preliminary.config



Cut Flow Definition

Similar cuts between jet pT and dijet mass measurement:

Item Cut
1 Total number of events
2 Number of events after GRL
3 Number of events after requiring larError == 0
4 Number of events after requiring Ntrk,PV[0] > 1
5 Total number of jets in events passing the above cuts
6 Number of jets with |y| < 2.8
7 Number of jets with pT ≥ 50 GeV

Additional cuts for jet (J) pT spectra:
Item Cut
8J Number of jets which pass BadLooseMinus and Ugly cleaning
9J Number of jets which pass trigger requirement
10J Number of events which contribute to inclusive jet pT spectra

Additional cuts for dijet (D) mass spectra (do NOT include additional cuts for jet pT (8J-10J) before these, but DO include the common cuts 1-7 on events and jets):
Item Cut
8D Number of events with Njets > 1
9D Number of events with pT,1 ≥ 100 GeV
10D Number of events after leading/sub-leading BadLooseMinus/Ugly cut
11D Number of events after LAr veto
12D Number of events after y* < 2.5
13D Number of events after trigger requirement



Results for R = 0.4 jets



Results for R = 0.6 jets
