Bjorken Sum Rule and pQCD frontier on the move
Roman S. Pasechnik, Dmitry V. Shirkov, Oleg V. Teryaev
The reasonableness of the use of perturbative QCD notions in the region close to the scale of hadronization, i.e., below $\lesssim 1 \GeV$ is under study. First, the interplay betw…
Bound state approach to the QCD coupling at low energy scales
M. Baldicchi, A. V. Nesterenko, G. M. Prosperi +2
We exploit theoretical results on the meson spectrum within the framework of a Bethe-Salpeter (BS) formalism adjusted for QCD, in order to extract an ``experimental'' coupling α_s^…
Nonpower Expansions for QCD Observables at Low Energies
D. V. Shirkov
A comprehensive review is presented of the progress made in further developing the ghost-free Analytic Approach to low-energy QCD since "QCD-97" meeting. It is now formulated as a…
Analytic Perturbation Theory and New Analysis of some QCD observables
D. V. Shirkov
Here, we report briefly two topics: 1) The latest version of ``Analytic Perturbation Theory" (APT) devised recently for the QCD observables both in the Euclidean and Minkowskian re…
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…
