论文摘要
广义横向动量依赖的Parton分布（GTMD），作为横向动量依赖的Parton分布（TMDS）和广义的Parton分布（GPD）的母亲的功能，编码了Hadros的最通用的Parton结构。我们在标量观众模型中计算了TWO的四个扭曲时间逆转奇数GTMD。我们研究了GTMD对活动夸克携带的纵向动量分数$ x $的依赖性和横向动量$ | \ vec k_t | $，用于定义为纵向动量的不同值$吗？此外，在本文中还研究了准TMD和准-GPD。
Generalized transverse momentum dependent parton distributions (GTMDs), as mother funtions of transverse momentum dependent parton distributions (TMDs) and generalized parton distributions (GPDs), encode the most general parton structure of hadrons. We calculate four twist-two time reversal odd GTMDs of pion in a scalar spectator model. We study the dependence of GTMDs on the longitudinal momentum fraction $x$ carried by the active quark and the transverse momentum $|\vec k_T|$ for different values of skewness $ξ$ defined as the longitudinal momentum transferred to the proton as well as the total momentum $|\vecΔ_T|$ transferred to the proton. In addition, the quasi-TMDs and quasi-GPDs of pion have also been investigated in this paper.
