Suppression of Quantum Corrections by Classical Backgrounds
arXiv:1401.2775 · doi:10.1103/PhysRevD.89.125004
Abstract
We use heat-kernel techniques in order to compute the one-loop effective action in the cubic Galileon theory for a background that realizes the Vainshtein mechanism. We find that the UV divergences are suppressed relative to the predictions of standard perturbation theory at length scales below the Vainshtein radius.
