Dijet transverse momentum imbalance, fragmentation functions and jet–track correlations in PbPb collisions at √s[subscript NN] = 2.76 TeV with CMS
Dijets in PbPb collisions at a nucleon–nucleon center-of-mass energy of 2.76 TeV are studied with the CMS detector at the LHC. It is shown that the fragmentation functions of jets into charged particle tracks with transverse momenta p[subscript T] > 4GeV/c in PbPb collisions are similar to those...

| Summary: | Dijets in PbPb collisions at a nucleon–nucleon center-of-mass energy of 2.76 TeV are studied with the CMS detector at the LHC. It is shown that the fragmentation functions of jets into charged particle tracks with transverse momenta p[subscript T] > 4GeV/c in PbPb collisions are similar to those in pp collisions, for both the leading and subleading jets. In addition, study of high statistics PbPb data acquired in 2011 shows that the quenching phenomenon exists up to highest jet p[subscript T] values in excess of 300 GeV/c. |
