Kurzfassung:
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 $$ \sqrt{s_{\mathrm{N}\;\mathrm{N}}}=5.02 $$ s N N = 5.02 TeV via correlations of charged particles with the jet axis in relative pseudorapidity (Δ η ), relative azimuth (Δ ϕ ), and relative angular distance from the jet axis $$ \varDelta \mathrm{r}=\sqrt{{\left(\varDelta \eta \right)}^2+{\left(\varDelta \phi \right)}^2} $$ Δ r = Δ η 2 + Δ ϕ 2 . This analysis uses data collected with the CMS detector at the LHC, corresponding to integrated luminosities of 404 μ b −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 quark-gluon plasma.
