C. Adler et al., Phys. Rev. Lett. 87, 112303 (2001)


Normalized multiplicity distribution of h-

dsig/dNh- vs Nh- for pT > 0.1 GeV/c , |eta| < 0.5. Systematic error on the vertical scale is estimated to be 10%. The systematic error on the horizontal scale is 6% for the entire range of multiplicity.

Ratio STAR/UA1 as function of pT

The errors given are the errors of the STAR data only and do not include the systematic errors from the scaling of the UA1 data to 130 GeV (i.e., the shaded region in Fig.2 lower panel). The STAR data is for the 5% most central collisions.

h- and h+ pseudorapidity (eta) distributions

All distributions are for 5% most central collisions. Data for pT > 0.1 GeV/c was directly measured. Data for pT > 0 was obtained by extrapolating the pT distribution as described in the paper. The correlated systematic error on the overall normalization is estimated to be 6% for pT > 0.1 GeV/c and 7% for pT > 0.
