AI 中文摘要
横向动量依赖的部分子分布函数是近年来备受关注的对象，因为它们对于研究质子的三维结构至关重要。这些twist-3分布对于理解诸如高能散射实验中观察到的束流单自旋不对称等现象非常重要。然而，由于缺乏直接的唯象拟合，目前人们不得不依赖简化的质子模型来获得这些twist-3分布。在本工作中，我们利用夸克靶模型计算了T-even twist-3夸克分布。
英文摘要
Transverse momentum dependent parton distributions are objects that have gained substantial attention in the recent past as they are crucial for studying the 3-D structure of proton. These distributions at twist-3 are important for understanding phenomena like beam single spin asymmetries, which are observed in high-energy scattering experiments. However, due to the unavailability of direct phenomenological fits, currently one has to rely on simplified models of the proton in order to obtain these twist-3 distributions. In this work, we present the calculation of T-even twist-3 quark distributions using the quark target model.
