Abstract

Modifications of the properties of jets in PbPb collisions, relative to those in pp collisions, are studied at a nucleon-nucleon center-of-mass energy of √sNN= 5.02 TeV via correlations of charged particles with the jet axis in relative pseudorapidity (Δη), p relative azimuth (Δφ), and relative angular distance from the jet axis Δr = √(Δη)2+ (Δφ)2. This analysis uses data collected with the CMS detector at the LHC, corresponding to integrated luminosities of 404 μb-1and 27.4 pb-1for PbPb and pp collisions, respectively. Charged particle number densities, jet fragmentation functions, and jet shapes are presented as a function of PbPb collision centrality and charged-particle track transverse momentum, providing a differential description of jet modifications due to interactions with the quark-gluon plasma.
