论文摘要
协变量的Parton模型被概括为以系统的方式描述夸克相关器。先前的结果是针对T型扭转横向动量分布函数(TMD)复制的,并且首次在此模型中评估了所有T-Even Twist-3 TMD。我们采用了评估完全不整合的夸克相关器的方法,这使我们能够了解不同TMD之间的模型特定关系。我们验证方法的一致性,呈现数值结果,并与可用的TMD参数化进行比较。
The covariant parton model is generalized to describe quark correlators in a systematic way. Previous results are reproduced for the T-even leading-twist transverse momentum dependent parton distribution functions (TMDs), and for the first time all T-even twist-3 TMDs are evaluated in this model. We apply the approach to evaluate the fully unintegrated quark correlator which allows us to understand the model-specific relations between different TMDs. We verify the consistency of the approach, present numerical results and compare to available TMD parametrizations.
