Two-particle azimuthal correlation of an identified particle in high-energy heavy-ion collisions at the RHIC-PHENIX

摘要

The recent results from two-particle azimuthal correlation analysis will be shown and discussed, especially on Mach-cone-like away-side jet modification and a ridge-like near-side structure as well as their dependence as a function of the trigger angle selection with respect to the reaction plane. A new idea to extend such analysis will be proposed at the end.
