"Figure 3d" of "Pseudorapidity dependence of particle production and elliptic flow in asymmetric nuclear collisions of $p$$+$Al, $p$$+$Au, $d$$+$Au, and $^{3}$He$+$Au at $\sqrt{s_{_{NN}}}=200$ GeV"

Midrapidity charged hadron $dN_{ch}/d\eta$ per participating quark pair ($N_{qp}$/2) as a function of the number of participating quarks ($N_{qp}$).

本数据集展示了中心快度（midrapidity）区间内，每对参与夸克（participating quark pair，N_qp/2）对应的带电强子单位快度产额dN_ch/dη随参与夸克总数（N_qp）的变化关系。
