Jet properties in PbPb and pp collisions at √sNN=5.02 TeV
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 (∆η), relative azimuth (∆φ), and relative...

| Summary: | 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 (∆η), relative
azimuth (∆φ), and relative angular distance from the jet axis ∆r = p
(∆η)

2. This
analysis uses data collected with the CMS detector at the LHC, corresponding to integrated
luminosities of 404 µb
−1 and 27.4 pb−1
for 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 quarkgluon
plasma. |
