Abstract
We present measurements of the pseudo-rapidity (η) distribution of charged particles (dNch/dη) produced within |η|≤ 3.5 in proton-antiproton collisions at s= of 630 and 1800 GeV. We measure dNch/dη at η = 0 to be 3.18±0.05(stat)±0.10(sys) at 630 GeV, and 3.95±0.02(stat)±0.13(sys) at 1800 GeV. Many systematic errors in the ratio of dNch dη at the two energies cancel, and we measure 1.26±0.01±0.04 for the ratio of dNch/dη at 1800 GeV to that at 630 GeV within |η|≤ 3. Comparing to lower energy data, we observe an increase faster than In(s) in dNch dη at η=0

TL;DR: In this article, the authors measured the charged-particle spectra at the BNL Relativistic Heavy Ion Collider (RHIC) time projection chamber and reported the average transverse momenta, total particle production, particle yield ratios, strangeness, and baryon production rates as a function of collision system and centrality.

Hadron production in nuclear collisions at RHIC and high density QCD

TL;DR: In this article, the first results on charged particle multiplicity at RHIC in the conventional eikonal approach and in the framework of high-density QCD were analyzed, and the predictions of high density QCD for the centrality, energy, and atomic number dependence of hadron production were outlined.
