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
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 conventional and analytic versions of perturbation theory with the ``massive'' form of the twist-four contribution. We show that conventional perturbation theory fails to reproduce the data, while the analytic version demonstrates good agreement with experiment.
