"Figure 14 Bottom-2015 $\pi^{-}$" 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 particle jet-$p_{T}$ separately for the 2012 and 2015 data. 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 jet-$p_{T}$ (horizontal). The top panel shows the results for jets that scatter forward relative to the polarized beam ($x_{F} > 0$), while the bottom panel shows jets that scatter backward to the polarized beam ($x_{F} < 0$).

本数据集呈现了柯林斯不对称性（Collins asymmetries）$A_{UT}^{sin(phi_S - phi_H)}$ 随粒子喷注横动量（jet-$p_T$）的分布关系，分别对应2012年与2015年的实验数据。图中误差棒代表统计不确定度，箱体的尺寸则分别表征$A_{UT}^{sin(phi_S - phi_H)}$（纵向）与喷注横动量（jet-$p_T$，横向）的系统不确定度。上子图展示了相对于极化束流向前散射的喷注结果（$x_F > 0$），下子图则展示了相对于极化束流向后散射的喷注结果（$x_F < 0$）。
