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…

IR renormalon effects and light mesons' elm form factor

Shahin S. Agaev

The pion and kaon electromagnetic form factors $F_{M} (Q^{2})$ are calculated at the leading order of pQCD using the running coupling constant method. In calculations a dependence of th…
