论文摘要
在本文中，我们从半包含深度非弹性散射，drell-yan，$ e^+e^ - $ nihihihitation中进行了第一个同时对数据进行QCD全局分析。因此，我们能够提取一组通用的非扰动函数，这些函数描述了这些反应中观察到的不对称性。我们的分析结果表明，高能量碰撞中的单个横向自旋不对称具有共同的起源。此外，我们与lattice QCD达成了第一个现象学共识，并在上下夸克张量费用上。
In this paper we perform the first simultaneous QCD global analysis of data from semi-inclusive deep inelastic scattering, Drell-Yan, $e^+e^-$ annihilation into hadron pairs, and proton-proton collisions. Consequently, we are able to extract a universal set of non-perturbative functions that describes the observed asymmetries in these reactions. The outcome of our analysis indicates single transverse-spin asymmetries in high-energy collisions have a common origin. Furthermore, we achieve the first phenomenological agreement with lattice QCD on the up and down quark tensor charges.
