Description
The PHENIX experiment was designed to excel at measurements of photons.
Direct photons provide a unique tool for measuring jet energy loss, because
they do not participate in the strong interaction and do not lose energy in
the QGP. At leading order the photons are produced with an opposing quark
jet, and the measurement of the photon energy provides a calibrated way to
determine the amount of energy lost by the quark in the medium. Measurements
of direct photon-hadron correlations in p+p, d+Au and Au+Au collisions may
reveal possible modifications of the quark fragmentation in Au+Au collisions
due to interactions with the medium. This talk will present the most recent
PHENIX results using direct photon-triggered correlations and compare these
measurements to pi0-hadron correlations in the same collision systems.
