Phys. Rev. D 3, 1805–1817 (1971)Infinity Suppression in Gravity-Modified Quantum ElectrodynamicsReceived 28 September 1970; published in the issue dated 15 April 1971 Computations of gravity-modified quantum electrodynamics are performed using nonpolynominal Lagrangian field-theory techniques. The inverse of the gravitational constant appears as an effective cutoff mass, and, in particular, it is shown that to order e2 the electron and photon self-energies are finite. The cutoff can be interpreted as if the electron had an intrinsic radius equal to its Schwarzschild radius. A central feature is the construction of the tensor gravity superpropagator. © 1971 The American Physical Society URL:
