"Figure 21, $K^{+}$, Right" 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-$p_{T}$, hadron-$z$, and hadron-$j_{T}$ for charged kaons (upper panels) and protons (lower panels) inside jets. In both cases, the $p_T$ dependence is shown integrated over the full ranges of $z$ and $j_T$, while the $z$ and $j_T$ dependences are shown integrated over detector jet-$p_T > 9.9$ GeV/$c$. The bars show the statistical uncertainties, while the size of the boxes represent the systematic uncertainties.

本数据集给出了带电K介子（上图面板）与质子（下图面板）在喷注内部的柯林斯不对称性（Collins asymmetries）$A_{UT}^{sin(phi_S - phi_H)}$，该物理量随粒子喷注横向动量$p_T$、强子动量份额$z$以及强子相对于喷注轴的横向动量$j_T$的变化关系。两组数据集（即带电K介子与质子的情况）中，其横向动量$p_T$的依赖关系均为在$z$与$j_T$的全部量程内积分所得；而$z$与$j_T$的依赖关系则为在探测器测量的喷注横向动量大于9.9 GeV/$c$的范围内积分所得。图中的误差棒代表统计不确定度，箱体的尺寸则对应系统不确定度。
