Pion form factor analysis using NLO analytic perturbation theory

N. G. Stefanis

I present results for the pion's electromagnetic form factor in the spacelike region, which implement the most advanced perturbative information currently available for this observ…

The gluon content of the $η$ and $η^{'}$ mesons

N. G. Stefanis, S. S. Agaev

We analyze power-suppressed contributions to singlet pseudoscalar $η$ and $η^{'}$ meson transition form factors. These corrections stem from endpoint singularities and help im…

Pion structure: from nonlocal condensates to NLO analytic perturbation theory

N. G. Stefanis, A. P. Bakulev, S. V. Mikhailov +2

A pion distribution amplitude, derived from nonlocal QCD sum rules, has been employed to calculate $F_{γ^{*} γ \to π} (Q^{2})$ using light-cone sum rules, and $F_{π} (Q^{2})$ in NLO QCD perturb…
