DREDed Anomaly Mediation
Full text linkWe offer a guide to dimensional reduction (DRED) in theories with anomaly
mediated supersymmetry breaking. Evanescent operators proportional to epsilon
arise in the bare Lagrangian when it is reduced from d=4 to d= (4-2 epsilon)
dimensions. In the course of a detailed diagrammatic calculation, we show that
inclusion of these operators is crucial. The evanescent operators conspire to
drive the supersymmetry-breaking parameters along anomaly-mediation
trajectories across heavy particle thresholds, guaranteeing the ultraviolet
insensitivity.Comment: 24 pages. 10 figures. Uses Axodraw. Reference adde
