The terms in the s-channel QCD observables
D. V. Shirkov
We analyze the effect of -terms in the QCD perturbative expansions for the s-channel effective coupling and observables, the effect known from the 80s. We remind that these te…

Toward the correlated analysis of perturbative QCD observables
D. V. Shirkov
We establish direct connection between ghost-free formulations of RG-invariant perturbation theory in the both Euclidean and Minkowskian regions. By combining the trick of resummat…
