Synthetic Running Coupling of QCD
Aleksey I. Alekseev
Based on a study of the analytic running coupling obtained from the standard perturbation theory results up to four-loop order, the QCD ``synthetic'' running coupling α_{syn} is bu…
An Invariant Charge Model for All q^2>0 in QCD and Gluon Condensate
A. I. Alekseev, B. A. Arbuzov
Under assumption of singular behavior of invariant charge alpha_s(q^2) at q^2 sim 0 and of large q^2 behavior, corresponding to the perturbation theory up to four loops, a procedur…
Beta-Function in QCD and Gluon Condensate
A. I. Alekseev, B. A. Arbuzov
Under assumption of singular behavior of alpha_s(q^2) at q^2 sim 0 and of large q^2 behavior, corresponding to the perturbation theory up to four loops, a procedure is considered o…
Strong coupling constant to four loops in the analytic approach to QCD
Aleksey I. Alekseev
The QCD analytic running coupling alpha_{an} which has no nonphysical singularities for all Q^2>0 is considered for the initial perturbation theory approximations up to four loop o…
Nonperturbative Contributions in an Analytic Running Coupling of QCD
Aleksey I. Alekseev
In the framework of analytic approach to QCD the nonperturbative contributions in running coupling of strong interaction up to 4-loop order are obtained in an explicit form. For al…
On dependence of nonperturbative contributions in on an initial approximation of perturbation theory in an analytic approach to QCD
Aleksey I. Alekseev
In the framework of analytic approach to QCD, which has been recently intensively developed, the dependence of nonperturbative contributions in a running coupling of strong interac…
