QCD Renormalons and Higher Twist Effects
Abstract
Description
I give a short review of the relation of infrared renormalons in QCD and higher twist effects, with the emphasis on possible applications. In particular, I present estimates of renormalon-induced uncertainties in deep inelastic sum rules and explain how the renormalons can potentially be used to unravel the structure of nonperturbative effects in complicated situations and to indicate possible systematic sources of large perturbative corrections.
