Title: Jet suppression and jet substructure in Pb+Pb and Xe+Xe collisions with the ATLAS detector

Abstract

This short summary presents latest measurements of the nuclear modification factor, R AA, for R = 0.4 jets in Pb+Pb collisions at √ sNN = 5.02 TeV with the ATLAS detector at the LHC. The analysis is performed over a large range of transverse momentum, up to p T = 1 TeV, and differentially in jet p T, rapidity, and collision centrality. The jet R AA is measured also differentially in the jet mass, m, which provides new information on the dependence of the energy loss on the substructure of jets. Latest results by ATLAS on the dijet momentum balance in Xe+Xe collisions at √ sNN = 5.44 TeV are presented and compared to the same quantity measured in Pb+Pb collisions at √ sNN = 5.02 TeV. Furthermore these recent measurements should help us understand mechanisms of parton energy loss and properties of hot and dense matter created in heavy-ion collisions.

Figure 1 Figure 1: The RAA values as a function of jet pT for jets with |y| < 2.1 in 0–10% and 30–40% centrality intervals compared to the same quantity measured in $\sqrt{sNN}$ = 2.76 TeV Pb+Pb collisions [6]. The error bars represent statistical uncertainties, the shaded boxes around the data pointsmore » quantify bin-wise correlated systematic uncertainties. For $\sqrt{sNN}$ = 2.76 TeV measurement, the open boxes represent uncorrelated systematic uncertainties. The coloured shaded boxes at RAA = 1 quantify the combined fractional 〈TAA〉 and pp luminosity uncertainty. The horizontal size of error boxes quantifies the width of the pT interval.
