Renormalons Beyond One-Loop
arXiv:hep-th/9611010 · doi:10.1103/PhysRevD.56.1091
Abstract
Higher order renormalons beyond the chain of one-loop bubbles are discussed. A perturbation method for the infrared renormalon residue is found. The large order behavior of the current-current correlation function due to the first infrared renormalon is determined in both QED and QCD to the first three orders.
