Using the leading-twist approximation of the Wilson operator product expansion with
“frozen” and analytic versions of the strong-coupling constant, we show that the Bessel …

In this paper we show that, as in the spacelike case, the inverse logarithmic expansion is
applicable for all values of the argument of the analytic coupling constant. We present two …

We study the heavy quark production processes with the transverse momentum dependent
(unintegrated) gluon distribution function in a proton which is obtained recently using the …

We investigate the two-gluon-exchange model of the Pomeron using nonperturbative gluon
propagators characterized by a dynamical mass scale. We present the results for an …

The product of the gluon dressing function and the square of the ghost dressing function in
the Landau gauge can be regarded to represent, apart from the inverse power corrections …

A method of evaluation of spacelike QCD observables D (Q 2) is developed, motivated by
the renormalon structure of these quantities. A related auxiliary quantity D˜(Q 2) is …

Deep inelastic scattering data on the F 2 structure function provided by the BCDMS, SLAC,
and NMC Collaborations are analyzed in the nonsinglet approximation with the analytic and …

Experimental data obtained for the polarized Bjorken sum rule (BSR) Γ _1^ pn (Q^ 2) Γ 1 pn
(Q 2) are fitted by using predictions derived within a truncated operator product expansion …

We study the QCD Adler function in the energy region≈ 0.7− 2.5 GeV, in which the non-
perturbative effects become dominant. Our analysis is a renormalon-based evaluation using …

In contrast to the coupling parameter in the usual perturbative QCD (pQCD), the coupling
parameter in the analytic QCD models has cuts only on the negative semiaxis of the Q 2 …
