✦ Synopsis

The PHENIX Run 4 Au+Au dataset provides a powerful opportunity for exploring the angular anisotropy of identified particle yields at high p T . Complementing traditional v 2 measurements, we present π 0 yields as a function of angle with reaction plane, up to p T 10 GeV/c. The centrality dependence of the angular anisotropy allows us to probe the density and path-length dependence of the energy loss of hard-scattered partons. We will discuss various mechanisms for particle production in this high p T region.
