横平面中的Angular Momentum分布

Angular Momentum Distribution in the Transverse Plane

Lekha Adhikari, Matthias Burkardt

摘要:

本文讨论了几种可能性,把广义部分子分布(GPD)的$t$依赖性与横平面角动量的分布联系起来。利用一个简单的旁观者模型,我们证明,没有一个正确地描述了轨道角动量分布的纵向极化核子直接获得的光波前波函数。

英文摘要:

Several possibilities to relate the $t$-dependence of Generalized Parton Distributions (GPDs) to the distribution of angular momentum in the transverse plane are discussed. Using a simple spectator model we demonstrate that non of them correctly describes the orbital angular momentum distribution that for a longitudinally polarized nucleon obtained directly from light-front wavefunctions.
