Jet Pt Spectrum Validation in Run 135149 with JetMET DQM Analysis

DESCRIPTION

This document presents an analysis of the Jet Pt spectrum during Run 135149 within the JetMET DQM framework. The analysis reveals a 0.3% reduction in entries compared to run 392, with a notable 7.8% decrease in jet yield in the endplug region. Approximately 13.3% of events fall within the Pt range of 10.0 - 10.5 GeV/c. It is anticipated that this correlates with a 10% reduction in energy in high-energy (HE) jets, alongside significant changes in the PF Neutral Hadron Fraction across |η| ranges from 1.3 to 3.0.

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
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.
