Abstract

We present the first measurement of pseudorapidity densities of primary charged particles near midrapidity in $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{\mathrm{NN}}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}56$ and $130\mathrm{GeV}$. For the most central collisions, we find the charged-particle pseudorapidity density to be $\mathrm{dN}/d\ensuremath{\eta}{|}_{|\ensuremath{\eta}|<1}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}408\ifmmode\pm\else\textpm\fi{}12(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}30(\mathrm{syst})$ at $56\mathrm{GeV}$ and $555\ifmmode\pm\else\textpm\fi{}12(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}35(\mathrm{syst})$ at $130\mathrm{GeV}$, values that are higher than any previously observed in nuclear collisions. Compared to proton-antiproton collisions, our data show an increase in the pseudorapidity density per participant by more than $40%$ at the higher energy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
