Di-jet correlation in Au + Au and Cu + Cu collisions from PHENIX
Jiangyong Jia
Abstract
PHENIX has measured the two particle azimuth correlation in Au + Au at s = 200 GeV. Jet shape and yield at the away side are found to be strongly modified at intermediate and low pT. The modifications vary dramatically with pT and centrality. At high pT, away side jet peak reappears but the yield is suppressed. Similar jet strength is found for Au + Au and Cu + Cu collisions with similar number of participant nucleons.
