Resumen
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 a measurement of the angular distribution of charged particles around the jet axis in
√
sNN = 5.02 TeV
Pb+Pb and pp collisions, done using the ATLAS detector at the LHC. The measurement is performed inside jets reconstructed
with the anti-kt algorithm with radius parameter R = 0.4, and is extended to regions outside the jet cone. Results
are presented as a function of Pb+Pb collision centrality, and both jet and charged-particle transverse momenta
