Abstract

The PHOBOS experiment at RHIC has measured large samples of Au+Au and Cu+Cu collisions using a detector with uniquely large angular acceptance. These data enable studies of particle production over a very wide pseudorapidity interval which reveal unexpected features. In the analysis of correlations with a high-p_T trigger particle (p_T > 2.5 GeV/c) a ridge extending at least 4 units of pseudorapidity was found. The results on forward-backward and two-particle correlations suggest that particles are produced in very large clusters which are wider in pseudorapidity than is expected for isotropic decays. Explanation of these experimental results requires models in which both short-range and long-range correlations are present.
