High-pT Particle Production with Respect to the Reaction Plane
David Winter
Abstract
The PHENIX Run4 data-set provides a powerful opportunity for exploring the angular anisotropy of identified particle yields at high pT. Complementing traditional v2 measurements, we present pi0 yields as a function of emission angle with respect to the reaction plane in Au+Au collisions at sqrt(s) = 200 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.
