Quantum-induced soft supersymmetry breaking in supergravity

We calculate the one-loop quantum contributions to soft supersymmetry breaking terms in the scalar potential in supergravity theories regulated a la Pauli-Villars. We find universal contributions, independent of the regulator masses and tree level soft supersymmetry breaking, that contribute gaugino masses and A-terms equal to the anomaly mediated contributions found in analyses using spurion techniques, as well as a scalar mass term not identified in those analyses. The universal terms are in general modified - and in some cases canceled - by model-dependent terms. Under certain restrictions on the couplings we recover the one-loop results of previous anomaly mediated supersymmetry breaking scenarios. We emphasize the model dependence of loop-induced soft terms in the potential, which are much more sensitive to the details of Planck scale physics than are the one-loop contributions to gaugino masses. We discuss the relation of our results to previous analyses. (C) 2000 Elsevier Science B.V. All rights reserved.
