论文摘要
我们利用一个简单的标量diquark模型来研究潜在的横向动量和潜在的角动量,该模型分别定义为横向动量和轨道角动量的Jaffe-Manohar和JI概念之间的差异。先前在晶格计算中已经发现了非变化的潜在角度动量,并且由于观众系统与高能量散射过程中的初始/最终状态相互作用的影响而被认为是出现的。这种重新分散现象本质上与负责产生士兵转移的人相似。这促使我们根据击中夸克的横向动量的期望值来寻找对潜在角动量的估计。
We make use of a simple scalar diquark model to study the potential transverse momentum and potential angular momentum, defined as the difference between the Jaffe-Manohar and Ji notions of transverse momentum and orbital angular momentum, respectively. A non-vanishing potential angular momentum has been previously found in lattice calculations and is believed to appear due to the effects of initial/final state interactions between the spectator system and the struck quark in high energy scattering processes. Such re-scattering phenomena are similar in nature to those who are responsible for generating the Sivers shift. This motivates us to search for an estimate of the potential angular momentum in terms of the expectation value of the transverse momentum of the struck quark.
