Medium effects on jet correlations in Au+Au and Cu+Cu collisions at PHENIX-RHIC

Abstract

Strong di-jet correlations have been observed in p+p and d+Au collisions at GeV at RHIC. It is important to study how this jet-correlation is affected by the hot, dense medium produced in heavy-ion collisions. In this contribution, we will study how the di-jet shape evolves in Au+Au and Cu+Cu collisions compared to p+p collisions, as well as examining the medium response to the jets. We will show the results and their dependence on the collision energy, geometry, trigger and associated particle pT, and particle types.
