Using two- and Three-particle correlations to probe strongly interacting partonic matter

Abstract

The latest two- and three-particle correlation measurements obtained by the PHENIX collaboration are presented. Three-particle correlations are consistent with the presence of conical emission patterns in the data. Two-particle correlations relative to the collision geometry reveal strong shape and yield modifications of the away-side jet, that depend on the orientation of the trigger particle with respect to the event plane. A difference in the geometry dependence of the per trigger yields in the regions around $\Delta \varphi \approx \pi$ and $\Delta \varphi \approx \pi \pm 1.1$ can be understood by a different geometry dependence of jet energy loss and the medium response to the deposited energy.
