"Supplemental Figure 1 p40pbar20_Beta_Binomial, 200 GeV" of "Measurement of the sixth-order cumulant of net-proton multiplicity distributions in Au+Au collisions at $\sqrt{s_{NN}}=$ 27, 54.4, and 200 GeV at RHIC"

Distributions of reconstructed protons (black circles) from embedding simulations in 200 GeV Au+Au collisions at 0-2.5% centrality. Red lines are fits with the binomial distribution, and green dotted lines represent the fit with the beta-binomial distributions using α that gives the minimal chi2/ndf. Each panel shows the result from the given combinations of embedded protons and antiprotons. The ratio of fits to the embedding data is shown for each panel.

本数据集展示了0-2.5%中心度的200GeV金金（Au+Au）碰撞中，嵌入模拟得到的重建质子分布（以黑色圆点标记）。其中红色曲线为二项分布拟合结果，绿色虚线则是采用使χ²/ndf取最小值的α参数所得的贝塔二项分布拟合结果。每个子图均呈现了嵌入质子与反质子的指定组合对应的分布结果，且各子图均同时给出了拟合结果与嵌入模拟数据的比值。
