abstract

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.

    The one-loop electroweak gravitational form factors of the Higgs give a finite theta2 and an energy radius r^2 approximately 1.44e-6 GeV^-2, with theta1 requiring an EFT counterterm.
