"Figure 3" of "Forward neutral pion production in p+p and d+Au collisions at s(NN)**(1/2) = 200-GeV."

Nuclear modification factor ($R_{dAu}$) for minimum-bias d+Au collisions versus transverse momentum ($p_{T}$). The solid circles are for $\pi^{0}$ mesons. The open circles and boxes are for negative hadrons [10]. The error bars are statistical, while the shaded boxes are point-to-point systematic errors. (Inset) $R_{dAu}$ for $\pi^{0}$ mesons with the ratio of curves in Figs. 2 and 1.

针对最小偏置氘金（d+Au）碰撞的核修正因子（Nuclear modification factor，$R_{dAu}$）随横动量（transverse momentum，$p_T$）的变化关系。其中实心圆点代表π⁰介子，空心圆点与方框代表负强子[10]。误差棒为统计误差，阴影方框则代表逐点系统误差。（插图）对应π⁰介子的核修正因子，其数值取自图2与图1中曲线的比值。
