论文摘要
我们在量子电动力学中以一个环的一个环计算电子的重力形式因子，将其分解为来自能量巨型张量的电子和光子部分的贡献。紫外线通过在$ \ overline {\ text {ms}} $方案中的重量化来删除紫外线。红外差异是分离的，结果均以维数正则化和光子质量正则化。形式因素包含有关QED中电子能量和角动量结构及其质量半径的信息。只要可能，我们将结果与现有文献进行比较。
We calculate the gravitational form factors of the electron at one loop in quantum electrodynamics, decomposing these into contributions from the electron and photon parts of the energy-momentum tensor. Ultraviolet divergences are removed through renormalization in the $\overline{\text{MS}}$ scheme. Infrared divergences are isolated and results are given in both dimensional regularization and photon-mass regularization. The form factors contain information about the electron's energy and angular momentum structure in QED, as well as its mass radius. Whenever possible, we compare our results with the existing literature.
