Description
The jet fragmentation function of inclusive jets with pT > 100 GeV/c in PbPb collisions is measured for reconstructed charged particles with pT > 1 GeV/c within the jet cone. A data sample of PbPb collisions collected in 2011 at a center of mass energy of √sNN =2.76 TeV corresponding to an integrated luminosity of Lint = 129 μb−1 is used. The results for PbPb collisions as a function of collision centrality are compared to reference distributions based on pp data collected at the same collision energy. For the most central collisions a significant rise of the PbPb/pp fragmentation function ratio for the softest fragmentation products with pT < 3 GeV/c is observed.
