Dyson-Schwinger calculations of meson form factors

Abstract

The ladder-rainbow truncation of the set of Dyson-Schwinger equations is used to study the pion and kaon electromagnetic form factors and the ${\gamma }^{\star }{\pi }^0\gamma$ transition form factor in impulse approximation. With model parameters previously fixed by the pseudoscalar meson masses and decay constants, the obtained form factors are in good agreement with the data.
