Threshold effects at two-loop level and parametrization of real QCD
Description
The differential renormalization group equation for the invariant coupling is solved in the two-loop approximation taking into account the finite-mass effects. This solution is used to analyse the behaviour of the QCD running coupling constant in the vicinity of the c anti c and b anti b thresholds. The quantitative law of variation of the dimensional scale parameter Λ which describes the transition from 3-quark to 5- and 6-quark regions is determined
