Jet Energy Correction with Charged Particle Tracks in CMS

The performance of a jet-energy-correction algorithm using reconstructed charged particle tracks is presented. The jet energy correction allows the jet energy scale to be restored and improves the energy resolution for jets with energies up to 120 GeV. For low energy jets (20 GeV) it improves the re...

description The performance of a jet-energy-correction algorithm using reconstructed charged particle tracks is presented. The jet energy correction allows the jet energy scale to be restored and improves the energy resolution for jets with energies up to 120 GeV. For low energy jets (20 GeV) it improves the resolution by a factor 1.7 with respect to uncorrected jets. For 100 GeV jets the resolution improves by 15%. The deviation from unity of the ratio of the reconstructed to the generator jet transverse energies decreases by a factor two for low-$\textrm{E}_\textrm{T}$ jets ($\textrm{E}_\textrm{T} \lt 30$ GeV). For high-$\textrm{E}_\textrm{T}$ jets, this ratio amounts to $1.00 \pm 0.04$.
