Electromagnetic angular momentum of the electron: One-loop studies
arXiv:1908.06061 · doi:10.1016/j.nuclphysb.2019.114828
Abstract
We study angular momentum of the electron stored in its electric and magnetic fields. We use for this purpose quantum electrodynamics in the covariant gauge. We show that a finite one-loop result for such angular momentum can be obtained without invoking any renormalization procedure. We compare it to the classical estimation relying on a short-distance cutoff.
