Transport model analysis of particle correlations in relativistic heavy ion collisions at femtometer scales

Abstract

The pion source as seen through HBT correlations at RHIC energies is investigated within the UrQMD approach. We find that the calculated transverse momentum, centrality, and system size dependence of the Pratt-HBT radii $R_L$ and $R_S$ are reasonably well in line with experimental data. The predicted $R_O$ values in central heavy ion collisions are larger as compared to experimental data. The corresponding quantity $\sqrt{R_O^2-R_S^2}$ of the pion emission source is somewhat larger than experimental estimates.
