Abstract

We present a systematic analysis of azimuthal correlations between inclusive photons detected in the STAR Barrel Electromagnetic Calorimeter and tracks measured in the Time Projection Chamber in p + p and d + Au collisions. These measurements provide insight in basic properties of jet fragmentation in p + p and d + Au collisions at RHIC energies and also serve as a reference for medium-modified fragmentation in nuclear collisions. The on-line trigger on high-pT photons in the Barrel Calorimeter provides a substantial sample of triggered events with photons at high-pT. Even at this pT, the photon sample is dominated by π0 decays, allowing to explore jet fragmentation with a leading π0 in detail.
