电子的Angular Momentum分解

Angular Momentum Decomposition for an Electron

Matthias Burkardt, Hikmat BC

摘要:

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($α$阶)。我们比较了从Jaffe-Manohar分解得到的轨道角动量和从Ji关系得到的轨道角动量,并估计了矢量势在轨道角动量定义中的重要性。

英文摘要:

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 $α$). 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.
