Observation of Au + Au → Au + Au + ρ 0 and Au + Au → Au ∗ + Au ∗ + ρ 0 with STAR

We report the first observation of the reactions + ρ 0 with the STAR detector. The ρ are produced at small perpendicular momentum, as expected if they couple coherently to both nuclei. We discuss models of vector meson production and the correlation with nuclear breakup, and present a fundamental test of quantum mechanics that is possible with the system.

Time evolution of relativistic d + Au and Au + Au collisions

The evolution of charged-particle production in collisions of heavy ions at relativistic energies is investigated as function of centrality in a nonequilibrium-statistical framework. Precise agreement with recent d + Au and Au + Au data at √ sNN = 200 GeV is found in a Relativistic Diffusion Model with three sources for particle production. Only the midrapidity source comes very close to local ...

Rapidity equilibration in d + Au and Au + Au systems

In a Relativistic Diffusion Model (RDM), the evolution of netproton rapidity spectra with √ sNN in heavy systems is proposed as an indicator for local equilibration and longitudinal expansion. The broad midrapidity valley recently discovered at RHIC in central Au + Au collisions at √ sNN= 200 GeV suggests rapid local equilibration which is most likely due to deconfinement, and fast longitudinal...
