Ultraviolet renormalon reexamined [PDF]

open access: yesPhysical Review D, 1996
We consider large-order perturbative expansions in QED and QCD. The coefficients of the expansions are known to be dominated by the so called ultraviolet (UV) renormalons which arise from inserting a chain of vacuum-polarization graphs into photonic (gluonic) lines.
