  1. 394 Data ValSkim Validation JetMET DQM and Validation Group

  2. Jet Pt Spectrum – Run 135149 • Top (394), Bottom (392). # of entries -0.3% wrt 392 # of entries -0.03% wrt 392 # of entries -7.8% wrt 392

  3. Cont’d • ~2500 (13.3%) events in Pt=10.0 - 10.5 GeV/c of the endplug PF jet Pt plots from 392. • Considering this, 7.8% jet yield reduction in the endplugcorresponds to about 2-3% jet pt reduction in 394. • We are expecting ~10% energy reduction in HE, and the PF Neutral Hadron Fraction changes from 10% to 40% in ranges of |eta| from 1.3 to 3.0 (PFT-10-002, Fig 11). • The observation appears consistent with the expectation.
