Event-by-event average $p_T$ fluctuations in PHENIX: measurements and jet contribution simulations

Abstract

Small, but significant non-random fluctuations in event-by-event average $p_T$ have been observed in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV by the PHENIX collaboration at RHIC. These are consistent with being caused by correlations due to jets at large $p_T$, where the measured suppression must be included to reproduce the centrality dependence of the non-random fluctuations.
