我们计算了标量双夸克模型中“夸克”的轨道角动量以及QED中电子的轨道角动量(阶数为$$\α$$)。我们比较了由Jaffe-Manohar分解得到的轨道角动量和由Ji关系得到的轨道角动量，并估计了矢势在轨道角动量定义中的重要性。
We calculate the orbital angular momentum of the `quark' in the scalar diquark model as well as that of the electron in QED (to order $$\alpha$$). We compare the orbital angular momentum obtained from the Jaffe-Manohar decomposition to that obtained from the Ji relation and estimate the importance of the vector potential in the definition of orbital angular momentum.
