AI 中文摘要
我们采用光锥形式体系内的重叠表示,研究了质子内部在零斜度下$\ar{u}$和$\ar{d}$夸克的twist-4广义横向动量依赖部分子分布(GTMDs)。利用从重子-介子涨落模型导出的、以$|q\ar{q}B\ angle$福克态表示的质子光锥波函数,我们计算了$\ar{u}$和$\ar{d}$夸克的twist-4 GTMDs。此外,我们的研究还探讨了GTMDs与广义部分子分布之间的复杂关系。我们分析并展示了这些twist-4 GTMDs和twist-4 GPDs在零斜度下的数值结果。
英文摘要
We investigate the twist-4 generalized transverse momentum dependent parton distributions (GTMDs) of $\bar{u}$ and $\bar{d}$ quarks inside the proton at zero skewness by adopting the overlap representation within the light-cone formalism. Using the light-cone wave functions of the proton derived from the baryon-meson fluctuation model in terms of the $|q\bar{q}B\rangle$ Fock states, we calculate the twist-4 GTMDs of $\bar{u}$ and $\bar{d}$ quarks. Additionally, the intricate relations between the GTMDs and the generalized parton distributions are also explored in our research. Numerical results for these twist-4 GTMDs and twist-4 GPDs at zero skewness are analyzed and presented.
