Abstract: (Elsevier)
We show that a distribution of virtual black holes in the vacuum at shorter than Planck scales can have a profound effect on the perturbative high-energy behavior of a quantum field theory. This follows if we make the assumption that only perturbations which vanish inside the apparent horizons of virtual black holes can make a coherent contribution to scattering amplitudes. As a result there is a cutoff-dependent contribution to the density of states which comes from the scale dependence of the density of virtual black holes in the vacuum. This results in a modification in the divergence-structure of perturbation theory on a background of spacetime foam.- black hole
