Abstract (Summary)

We present plots of the pattern of particle formation in [special characters omitted] = 200 GeV Au+Au heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) using three different two-particle correlation measurements of number and transverse momentum as a function of relative azimuth, pseudorapidity and centrality. All three observables show the onset with increasing centrality of a near-side "ridge" of enhanced correlations in pseudorapidity. The plots of real data are compared to plots of simulations using RQMD data and data from a simple "cluster" model. RQMD (relativistic quantum molecular dynamics) program uses a transport theoretical model of hadron collisions. The "cluster" dataset is a simplistic cartoon of a decay event involving an invariant mass that receives a longitudinal and then transverse Lorentz boost. The effect of radial flow on clusters is shown with a radial boost applied both collectively and to individual clusters. We find that the kinematic effect of radial flow in simulated cluster data produces a near-side "ridge" similar to that seen in the data.
