Renormalons Beyond One-Loop
نویسنده
چکیده
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.

Naive nonabelianization and resummation of fermion bubble chains
We propose to extend the Brodsky-Lepage-Mackenzie scale-fixing prescription by resumming exactly any number of one-loop vacuum polarization insertions into one-loop diagrams. In this way, one makes maximal use of the information contained in one-loop perturbative corrections combined with the one-loop running of the effective coupling. The scale ambiguity at leading order is converted into an i...
متن کاملA Quick Look at Renormalons *
Renormalons as a pure theoretical construct are known since 1977 [1]. The first attempts to develop a renormalon-based phenomenology are more recent [2,3]. Nowadays it is a fast developing field and a concise review is obviously beyond the scope of the present contribution. Instead, this paper is a compromise between an original paper and a mini-review. Namely we try to put the topics discussed...
متن کاملRunning coupling at small momenta, renormalization schemes and renormalons
We suggest a method of summing the perturbation theory (PT) asymptotic series related to infrared (IR) renormalons in QCD by using special renormalization schemes in which the running coupling can be integrated over the region of small momenta. For the method to work, one should consider higher order PT corrections to the standard bubble-chain diagrams. High-order corrections allow one to choos...
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...
متن کاملLarge-order Behaviour due to Ultraviolet Renormalons in QCD
Ultraviolet renormalons, contrary to their infrared counterparts, lead to a universal contribution to the large-order behaviour of perturbative expansions in QCD. In this letter, we determine nature of the leading ultraviolet renormalon singularity for the inclusive hadroproduction cross section in ee annihilation, for hadronic τ decays and the moments of deep-inelastic scattering structure fun...
