Abstract
Studies of the fragmentation of jets into charged particles in heavy-ion collisions can help in understanding the mechanism of jet quenching by the hot and dense QCD matter created in such collisions, the quark-gluon plasma. These proceedings present measurements of the fragmentation functions of inclusive jets, the angular distribution of charged particles in and around such jets, and the fragmentation functions of photon-tagged jets, in $\sqrt{s_{\mathrm{NN}}}=$5.02TeV Pb+Pb and \textit{pp} collisions, done using the ATLAS detector at the LHC. The measurements are performed for jets reconstructed with the anti-$k_{t}$ algorithm with radius parameter $R = 0.4$.
