Angular Correlations in STAR
  The related studies of two-particle correlations and event-by-event fluctuations have played important roles in the search for new physics through the experimental study of relativistic heavy ion collisions. We present a general method of determining minimum-bias two-particle correlations and show the relationship between these correlations and event-by-event fluctuations. Data from the STAR experiment at RHIC for Au-Au collisions at $\sqrt{s_{NN}}$ = 62 and 200 GeV will be presented that show the energy and centrality dependences of angular correlations. This analysis provides a unique method for studying the interaction of semi-hard scattered partons with the dense medium produced at RHIC as well as properties of the bulk medium itself, and will shed new light on the sources of non-statistical fluctuations.
