Datasets

  • Real data:

data11_7TeV.*.physics_ JetTauEtmiss.merge.NTUP_SMQCD.*_p621/

– Integral luminosity 1.031 fb-1 – Trigger EF_j240_a4tc_EFFS is used

  • Monte Carlo: mc10_7TeV.*.J*_

pythia_jetjet.merge.NTUP_SMQCD.*_p621/

  • MC histograms merged by hadd.C – different JX

samples (1-8) are weighted

  • Jet reconstruction algorithm AntiKT4 is used

Energy plots

  • Data are split by rapidity and by reconstructed

pT of jets

– pT bins are 20 GeV/c wide

  • Mean values of jet energy deposition in parts
  • f calorimeter are calculated for every bin

Conclusions

  • It is necessary to fix a pileup bug in

Monte Carlo (peaks about 200 GeV/c)

– By cuting the pT interval of Jx sample – By cuting the distance between truth and real primary vertex position
