论文摘要
WORM-GEAR-T函数参数可以在横向极化的强子内找到纵向极化的夸克的概率。我们从在指南针和爱马仕测得的极化半含量深度弹性散射（SIDIS）中提取它。作为一个理论模型，我们在临时领先的顺序下使用wandzura-wilczek型近似。我们发现，目前，数据质量不足以忠实地确定Worm-Gear-T功能。我们还提供了与与蠕虫 - 胶合函数相关的横向单旋旋转不对称的预测，该功能可以在Star的弱玻色子产生中进行测量。
The worm-gear-T function parameterizes the probability to find a longitudinally polarized quark inside a transversely polarized hadron. We extract it from data on polarized semi-inclusive deep-inelastic scattering (SIDIS) measured at COMPASS and HERMES. As a theoretical model, we use a Wandzura-Wilczek-type approximation at the next-to-leading order. We find that, at present, the data quality is insufficient to determine the worm-gear-T function faithfully. We also provide predictions for the transverse single-spin asymmetry associated with the worm-gear-T function, which could be measured in weak-boson production at STAR.
