"Figure 24 Mid Down $\pi^{+}$" of "Azimuthal transverse single-spin asymmetries of inclusive jets and identified hadrons within jets from polarized $pp$ collisions at $\sqrt{s}$ = 200 GeV"

Collins asymmetries, $A_{UT}^{\sin(\phi_{S}-\phi_{H})}$, as a function of the charged pion's momentum transverse to the jet axis, $j_{T}$, in different hadron longitudinal momentum fraction $z$ bins, integrated over detector jet-$p_T > 9.9$ GeV/$c$. The bars show the statistical uncertainties, while the size of the boxes represents the systematic uncertainties on $A_{UT}^{\sin(\phi_{S}-\phi_{H})}$ (vertical) and hadron-$j_{T}$ (horizontal).

本数据集包含柯林斯不对称性（Collins asymmetries）$A_{UT}^{sin(phi_S - phi_H)}$，该量以带电π介子相对于喷注轴的横向动量$j_T$为自变量，覆盖不同强子纵向动量份额$z$区间，且在探测器测得的喷注横向动量$p_T>9.9$ GeV/$c$的条件下积分得到。图中误差棒代表统计不确定度，箱体的尺寸则分别表示$A_{UT}^{sin(phi_S - phi_H)}$（垂直方向）与强子-$j_T$（水平方向）的系统不确定度。
