"Figure 22 TOP-Left $\pi^{+}$" 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 longitudinal momentum fraction, $z$, in different jet-$p_{T}$ bins. 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-$z$ (horizontal).柯林斯不对称性（Collins asymmetries）$A_{UT}^{sin(phi_S-phi_H)}$ 随不同喷注横向动量（jet-$p_T$）区间内带电π介子（pion）的纵向动量份额$z$的变化关系。其中误差棒代表统计不确定度，方框的尺寸分别对应$A_{UT}^{sin(phi_S-phi_H)}$（纵轴）与强子$z$（横轴）的系统不确定度。
