We present an update to the QCD global analysis of single transverse-spin asymmetries presented in [J. Cammarota et al. (Jefferson Lab Angular Momentum Collaboration), Phys. Rev. D 102, 054002 (2020).] (JAM3D-20). JAM3D-20 simultaneously included transverse momentum dependent and collinear twist-3 observables, both of which are sensitive to quark-gluon-quark correlations in hadrons. In this study we extract for the first time the twist-3 chiral odd fragmentation function $\tilde{H}$ by incorporating the $\sin {\varphi }_s$ modulation data from semi-inclusive deep-inelastic scattering along with its contribution to the single transverse-spin asymmetry in pion production from proton-proton collisions. We also explore the impact of lattice QCD tensor charge calculations and the Soffer bound on our global analysis. We find that both constraints can be accommodated within our results, with $\tilde{H}$ playing a key role in maintaining agreement with the data from proton-proton collisions.

更新了单横向自旋不对称性的 QCD 全局分析：提取 H~，以及 Soffer 绑定和晶格 QCD 的作用

我们对 [J. 卡马罗塔等人。（杰斐逊实验室角动量合作），物理学。修订版 D 102，054002 (2020)。] ( JAM3D-20 )。JAM3D-20同时包括横向动量相关和共线扭曲 3 可观测量，两者都对强子中的夸克-胶子-夸克相关性敏感。在这项研究中，我们首次提取了twist-3手性奇数碎裂函数$\stackrel{～}{H}$通过纳入$罪{\phi }_s$来自半包容性深非弹性散射的调制数据及其对质子 - 质子碰撞产生的单横向自旋不对称性的贡献。我们还探讨了晶格 QCD 张量电荷计算和 Soffer 界对我们的全局分析的影响。我们发现这两个约束都可以包含在我们的结果中，其中$\stackrel{～}{H}$在与质子-质子碰撞数据保持一致方面发挥关键作用。
