Infrared Renormalons and Power Suppressed Effects in e+e− Jet Events
We study the effect of infrared renormalons upon shape variables that are commonly used to determine the strong coupling constant in e+e− annihilation into hadronic jets. We consider the model of QCD in the limit of large nf . We find a wide variety of different behaviours of shape variables with respect to power suppressed effects induced by infrared renormalons. In particular, we find that ob...
متن کاملInfrared Renormalons and Power Corrections in Deep-inelastic Sum Rules
Infrared renormalons and 1/Q2 power corrections in deep-inelastic sum rules are studied. The renormalization of operators with power divergence are discussed. The higher-twist terms in the operator product expansion are shown to account for the residual soft contributions survived from the Kinoshita-LeeNauenberg type of cancellation in Feynman diagrams. The presence of some degree of arbitrarin...
متن کاملRenormalons and Power Corrections
Even for short-distance dominated observables the QCD perturbation expansion is never complete. The divergence of the expansion through infrared renormalons provides formal evidence of this fact. In this article we review how this apparent failure can be turned into a useful tool to investigate power corrections to hard processes in QCD.
متن کاملInfrared Renormalons and Finite Volume *
We analyze the perturbative expansion of a condensate in the O(N) non-linear sigma model for large N on a two dimensional finite lattice. On an infinite volume this expansion is affected by an infrared renormalon. We extrapolate this analysis to the case of the gluon condensate of Yang-Mills theory and argue that infrared renormalons can be detected by performing perturbative studies even on re...
متن کاملBeta function and infrared renormalons in the exact
We discuss the relation between the Gell-Mann-Low beta function and the " flowing couplings " of the Wilsonian action S Λ [φ] of the exact renormalization group (RG) at the scale Λ. This relation involves the ultraviolet region of Λ so that the condition of renormalizability is equivalent to the Callan-Symanzik equation. As an illustration, by using the exact RG formulation, we compute the beta...
