QCD analytic coupling
I. A. Zemlyakov, I. L. Chuev, A. V. Kotikov
A brief overview of QCD analytic coupling is presented, mainly following the results obtained in [1]. An application to the pion-photon transition form factor is demonstrated.
Pion-photon transition form factor with analytic coupling
I. A. Zemlyakov, I. L. Chuev, A. V. Kotikov
We investigate the pion-photon transition form factor within the framework of analytic QCD. A comparison is performed between experimental data and perturbative QCD based on conven…
Analytic QCD: Recent Results
A. V. Kotikov, I. A. Zemlyakov
We present a brief overview of analytical QCD, focusing primarily on a less common form of the analytical coupling A_{\rm MA}(Q^2), which is particularly convenient for Q^2\simÎ^2…
QCD with Analytic Coupling: Recent Results
I. R. Gabdrakhmanov, N. A. Gramotkov, A. V. Kotikov +3
This work provides an overview of recent results obtained in the framework of QCD with analytic coupling. Applications to the polarized Bjorken and Gross-Llewellyn Smith sum rules…
On Bjorken sum rule: heavy quarks and analytic coupling
I. R. Gabdrakhmanov, N. A. Gramotkov, A. V. Kotikov +3
We present the results of [1], where good agreement was obtained between calculations within the framework of analytic QCD and experimental data on polarized Bjorken sum rule. The…
