Two-loop Anomalous Dimensions for Four-Fermi Operators in Supersymmetric Theories

Abstract

We derive two-loop anomalous dimensions for four-Fermi operators in supersymmetric theories using the effective Kahler potential. We introduce the general forms in generic gauge theories and apply our results to the flavor-changing operators in (minimal) supersymmetric standard models.Comment: 20 pages, Version accepted for publication in Nuclear Physics
