Measurement of angular and momentum distributions of charged particles within and around jets with the ATLAS detector

Studies of the fragmentation of jets into charged particles in heavy-ion collisions can provide information about the mechanism of jet-quenching by the hot and dense QCD matter created in such collisions, the quark-gluon plasma. This talk presents a measurement of the angular distribution of charged particles around the jet axis in 5.02 TeV Pb+Pb and pp collisions, using the ATLAS detector at the LHC. The Pb+Pb and pp data sets have integrated luminosities of 0.49/nb and 25/pb, respectively.
