Abstract
The modification of jet shapes in Pb-Pb collisions, relative to those in pp collisions, is studied for jets
associated with an isolated photon. The data were collected with the CMS detector at the LHC at a nucleonnucleon center-of-mass energy of 5.02 TeV. Jet shapes are constructed from charged particles with track
transverse momenta (pT ) above 1 GeV=c in annuli around the axes of jets with pjet
T > 30 GeV=c
associated with an isolated photon with pγ
T > 60 GeV=c. The jet shape distributions are consistent between
peripheral Pb-Pb and pp collisions, but are modified for more central Pb-Pb collisions. In these central PbPb events, a larger fraction of the jet momentum is observed at larger distances from the jet axis compared
to pp, reflecting the interaction between the partonic medium created in heavy ion collisions and the
traversing partons.
