Abstract

The measurement of γ+jet events with a direct photon in coincidence with an energetic parton can provide unique insights into the propagation and fragmentation of the parton in the presence of the hot and dense medium created in heavy-ion collisions. One way to explore these effects is the study of azimuthal correlations between the direct photon and hadrons produced in the fragmentation.

We present azimuthal correlations between photons with a transverse momentum of more than 10 GeV and charged hadrons with a transverse momentum of more than 2 GeV in Au+Au collisions at View the MathML source that have been measured with the STAR detector at RHIC. The separation of correlations with direct photons and photons from hadronic decays will be discussed.
