Modification of jet-like correlations in Pb - Au collisions at 158A GeV/c
Results of a two-particle correlation analysis of high-pt charged particles in Pb–Au collisions at 158A GeV/c are presented. The data have been recorded by the CERESexperiment at the CERN-SPS. The correlations are studied as function of transverse momentum, particle charge and collision centrality....

| description | Results of a two-particle correlation analysis of high-pt charged particles in Pb–Au collisions at 158A GeV/c are presented. The data have been recorded by the CERESexperiment at the CERN-SPS. The correlations are studied as function of transverse momentum, particle charge and collision centrality. We observe a jet-like structure in the vicinity of a high-pt trigger particleand a broad back-to-back distribution. The yields of associated particles per trigger show a strongdependence on the trigger/associate charge combination. A comparison to PYTHIA confirmsthe jet-likepattern at the near-side but suggestsa strongmodification at the away-side, implyingsignificant energy transferof the hard-scattered parton to the medium. |
