High- p T γ-hadron and π 0 -hadron correlations in √ s NN =200 GeV Au+Au collisions in PHENIX

Abstract

This poster presents the PHENIX results on high-p Tγ-hadron and π0-hadron correlations and shows the modification of away side jet shape by the medium. By comparing their jet shapes and yields, we see some evidence of the direct γ contribution to correlation functions.
