Correlations and Fluctuations at RHIC

Abstract

Particle correlations and fluctuations measured by RHIC experiments at $\sqrt{s_{NN}}$=130 GeV were discussed. The source size parameters were similar to those measured at the CERN-SPS, and no long duration time of particle emission were observed. It was pointed out that the dependences of longitudinal and transverse radius parameters on the pair momentum are explained with a single $m_T$ scaling function observed at the SPS energy. Fluctuation studies of mean $p_T$ of charged particles and of mean $E_T$ in an electromagnetic calorimeter found no significant non-statistical fluctuations by PHENIX, but some indication in charge independent $<p_T>$ by STAR.
