Renormalons and perturbative fixed points

Abstract

The connection between renormalons and power corrections is investigated for the typical infrared renormalon integral assuming the effective coupling constant has an infrared fixed point of an entirely perturbative origin. It is shown the full answer differs from the Borel sum by a power correction.
