The One-Loop Effective Kähler Potential. I: Chiral Multiplets

Abstract

We derive a universal formula for the one-loop renormalization of the effective Kähler potential that applies to general supersymmetric effective field theories of chiral multiplets, with arbitrary interactions respecting N=1 supersymmetry in four dimensions. The resulting expression depends only on the tree-level mass spectrum and the form of the regulator. This formula simplifies and generalizes existing results in the literature. We include two examples to illustrate its use.
