Generalization of BLM procedure and its scales in any order of pQCD: a practical approach

Creators

Description

Brodsky-Lepage-Mackenzie procedure is sequentially extended for any fixed order of the perturbation QCD. The reformed perturbation series looks like a continued fraction. A generalization of this procedure which provides one with a certain mechanism of the Fastest Apparent Convergence (FAC) prescription is developed. This generalized BLM procedure is applied to Adler function D in N3LO and N4LO. The final effect of this generalized BLM improvement for D and Re+e- functions is discussed
