摘要:

本文利用由软壁AdS/QCD预言构造的波函数,给出了核子的轻前夸克-双夸克模型中T偶TMD的结果。讨论了TMD之间的关系。将TMD的$p_\perp$依赖性与GPD的$t$依赖性进行比较。AdS/QCD波函数解释了在格点TMD计算中观察到的近似$x$和$p_\perp$分解。

英文摘要:

We present the results of T-even TMDs in a light front quark-diquark model of nucleons with the wave functions constructed from the soft-wall AdS/QCD prediction. The relations amongst TMDs are discussed. The $p_\perp$ dependence of the TMDs are compared with the $t$-dependence of the GPDs. AdS/QCD wave function provides an explanation behind the approximate $x$ and $p_\perp$ factorization observed in lattice TMD calculations.
