Özet
The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding to integrated luminosities of 150 μb− 1 and 5.3 pb− 1 respectively, were collected at a nucleon–nucleon centre-of-mass energy of s NN= 2.76 TeV with the CMS detector at the LHC. The jets are reconstructed with the anti-k T algorithm with a distance parameter R= 0.3, and the jet shapes are measured for charged particles with transverse momentum p T> 1 GeV/c. The jet shapes measured in PbPb collisions in different collision centralities are compared to reference distributions based on the pp data. A centrality-dependent modification of the jet shapes is observed in the more central PbPb collisions, indicating a redistribution of the energy inside the jet cone. This measurement provides …
