The centrality dependence of transverse energy and charged particle multiplicity at RHIC: Statistical model analysis
The transverse energy and charged particle multiplicity at midrapidity and
their ratio are evaluated in a statistical model with the longitudinal and
transverse flows for different centrality bins at RHIC at
and 200 GeV. Full description of decays of hadron resonances is applied in
these estimations. The predictions of the model at the freeze-out parameters,
which were determined independently from measured particle yields and
spectra, agree qualitatively well with the experimental data. The observed
overestimation of the ratio can be explained for more central collisions by the
redefinition of .Comment: Revtex, 8 figures (included), 11 pages. This is the final version
