Abstract (english)
The jet radial structure and particle transverse momentum (pT) composition within jets are presented in centrality-selected Pb–Pb collisions at √sNN=2.76 TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of R=0.3 at midrapidity |ηch jet|<0.6 for transverse momenta pT, ch jet=30 –120 GeV/ c . Jet–hadron correlations in relative azimuth and pseudorapidity space ( Δφ, Δη ) are measured to study the distribution of the associated particles around the jet axis for different pT, assoc -ranges between 1 and 20 GeV/c . The data in Pb–Pb collisions are compared to reference distributions for pp collisions, obtained using embedded PYTHIA simulations. The number of high- pT associate particles (pT, assoc<4, 20> GeV/c) in Pb–Pb collisions is found to be suppressed compared to the reference by 30 to 10%, depending on centrality. The radial particle distribution relative to the jet axis shows a moderate modification in Pb–Pb collisions with respect to PYTHIA. High- pT associate particles are slightly more collimated in Pb–Pb collisions compared to the reference, while low- pT associate particles tend to be broadened. The results, which are presented for the first time down to pT, ch jet=30 GeV/c in Pb–Pb collisions, are compatible with both previous jet–hadron- related measurements from the CMS Collaboration and jet shape measurements from the ALICE Collaboration at higher pT , and add further support for the established picture of in- medium parton energy loss.
