Measurements of jet quenching with semi-inclusive charged jet distributions in $Au+Au$ collisions at $\sqrt{s_{NN}}$=200 GeV

Abstract

We report measurements of jet quenching in $Au+Au$ collisions at $\sqrt{s_{NN}}$=200 GeV, based on the semi-inclusive distribution of reconstructed charged particle jets recoiling from a high $p_T$ hadron trigger. Jets are reconstructed with the anti-k${}_T$ algorithm ($R$=0.2 to 0.5), with low IR-cutoff of track constituents ($p_T>0.2$ GeV/c). Uncorrelated background is corrected using a novel mixed-event technique, with no fragmentation bias imposed by the correction procedure on the accepted recoil jet population. Corrected recoil jet distributions, reported in the range $0<p_{T,jet}^{ch}<30$ GeV/c, are used to measure jet yield suppression, jet energy loss, and intra-jet broadening. The first search for QCD Molière scattering of jets in hot QCD matter at RHIC is reported.
