The balance function versus $\Delta y$ for identified pion pairs from a) central and peripheral Au+Au collisions at $\sqrt{s_{NN}}$ = 130 GeV, and b) HIJING events simulated in GEANT [16]. To guide the eye, Gaussian fits excluding the lowest two bins in $\Delta y$ are shown. The error bars shown are statistical. The balance function for HIJING events is independent of centrality.

Ratio of Au+Au and p+p for small-angle ($|\Delta\phi|$<0.75 rad) and back-to-back ($|\Delta\phi|$<2.24 rad) azimuthal regions versus number of participating nucleons ($N_{\rm part}$) for trigger particle intervals $4<p_T^{\rm trig}<6$ GeV/$c$ and $3<p_T^{\rm trig}<4$ GeV/$c$.

Systematic uncertainty on number of participating nucleons ($N_{\rm part}$) in Au+Au collisions.

Centrality dependence of $⟨p^{trunc}_T⟩$, the average $p_T$ of charged particles with $p_T$ above a threshold $p^{min}_T$ minus the threshold $p^{min}_T$. Shown are values for two $p^{min}_T$ cuts, one at $p_T >$ 0.5 GeV/$c$ representing all data presented in Fig. 2 and the other one at $p_T >$ 2 GeV/$c$.

Nuclear modification factor ($R_{AA}$) for the 60-80%, 30-60%, 15-30%, and 5-15% centrality selections compared to the one for the most central sample (0-5%). Due to insufficient statistics $R_{AA}$ is not shown for the 80-92% sample.

The top panel gives the nuclear modification factor $R_{AA}$ for three exclusive $p_T$ regions as a function of the centrality of the collision. The lower panel shows essentially the same quantity but normalized to the number of participant pairs rather than to the number of binary collisions. The dotted line indicates the expectation for scaling with the number of binary collisions (top) or with the number of participants (bottom). Only statistical errors are shown. The systematic error on the scale and the centrality dependence are identical to the errors shown in Fig. 5. These errors are correlated, i.e. take their maximum or minimum value simultaneously for all centrality and $p_T$ selections. In addition, there are also $p_T$ dependent systematic errors, which are given in Table 1. The systematic errors do not alter the trends in the data.
