Title: PHENIX Measurement of High-p T Hadron-Hadron and Photon-Hadron Azimuthal Correlations

Abstract

High-p{sub T} hadron-hadron correlations have been measured with the PHENIX experiment in Cu and pp collisions at {radical}s{sub NN}=200 GeV. A comparison of the jet widths and yields between the two colliding systems allows us to study the medium effect on jets. We also present a first measurement of direct photon-hadron correlations in Au and pp collisions. We find that the near-side yields are consistent with zero in both systems. By comparing the jet yields on the away side, we observe a suggestion of the expected suppression of hadrons associated with photons in Au collisions.
