论文摘要
我们研究了Gluon Parton密度[Parton分布函数（PDF），横向动量分布（TMD），广义Parton分布（GPD）]和软壁ADS/QCD中的形态。我们表明，在光锥变量的较大值和平方动量的大值下，Gluon Parton分布的功率行为和形式因素与夸克计数规则一致。我们还表明，在我们的方法中得出的横向动量分布遵守模型独立的Mulders-Rodrigues不等式，而无需指代特定的模型参数。所有Gluon Parton分布均根据非极化和极化的GLUON PDF和配置功能定义。后者通过微分方程与Gluon PDF有关。
We study the gluon parton densities [parton distribution functions (PDFs), transverse momentum distributions (TMDs), generalized parton distributions (GPDs)] and form factors in soft-wall AdS/QCD. We show that the power behavior of gluon parton distributions and form factors at large values of the light-cone variable and large values of square momentum is consistent with quark counting rules. We also show that the transverse momentum distributions derived in our approach obey the model-independent Mulders-Rodrigues inequalities without referring to specific model parameters. All gluon parton distributions are defined in terms of the unpolarized and polarized gluon PDFs and profile functions. The latter are related to gluon PDFs via differential equations.
