We present charged particle densities as a function of pseudorapidity and collision centrality for the 197Au+197Au reaction at Sqrt{s_NN}=200 GeV. For the 5% most central events we obtain dN_ch/deta(eta=0) = 625 +/- 55 and N_ch(-4.7<= eta <= 4.7) = 4630+-370, i.e. 14% and 21% increases, respectively, relative to Sqrt{s_NN}=130 GeV collisions. Charged-particle production per pair of participant nucleons is found to increase from peripheral to central collisions around mid-rapidity. These results constrain current models of particle production at the highest RHIC energy.

Discussion (0). Continue with ORCID to comment.

  1. Centrality dependence of charged-hadron pseudorapidity distributions in oxygen-oxygen collisions at $\sqrt{s_\mathrm{NN}}$ = 5.36 TeV

    nucl-ex 2026-06 accept novelty 8.0 of 10

    First measurement of dNch/dη in OO collisions at 5.36 TeV yields midrapidity densities of 41.8 overall and 135 in central events, consistent with PbPb per participant but showing deviations from simple scaling.

  2. Longitudinal Dynamics of Large and Small Systems from a 3D Bayesian Calibration of RHIC Top-energy Collision Data

    nucl-ex 2026-01 conditional novelty 6.0 of 10

    A 3D Bayesian calibration of RHIC Au-Au and d-Au data constrains the longitudinal initial state and QGP viscosity, and its posterior predicts p-Au and 3He-Au flow measurements.

  3. Disentangling Initial-State and Evolution Effects in Heavy-Ion Collisions Using EPOS and PHSD

    hep-ph 2025-09 conditional novelty 5.0 of 10

    By swapping initial conditions and evolution engines between EPOS and PHSD, the authors find that the dynamical evolution stage, not the initial state, dominates final hadron spectra and elliptic flow in 200 GeV Au+Au...
