The electron-graviton interaction can be described in terms of the gravitational form factors of the QED energy-momentum tensor. Here we focus on the form factor $D(t)$, and we examine its properties and its interpretation in terms of internal forces at one-loop accuracy in QED. We perform the calculation by keeping separate the contributions due to the electron and the photon parts of the energy-momentum tensor. We also study the case of a nonzero photon mass. Furthermore, we discuss similarities with and differences to the form factor $D(t)$ of hadronic bound states.

电子的引力形状因子 D(t)

电子-引力子相互作用可以用 QED 能量-动量张量的引力形式因子来描述。在这里，我们专注于外形$D(吨)$，我们在 QED 中以单环精度检查其属性及其内力解释。我们通过将能量-动量张量的电子和光子部分的贡献分开来进行计算。我们还研究了非零光子质量的情况。此外，我们讨论了与外形的异同$D(吨)$ 强子束缚态。
