Abstract
The ladder-rainbow truncation of the set of Dyson-Schwinger equations is used to study a variety of electroweak and strong processes involving light mesons. The parameters in the effective interaction are constrained by the chiral condensate and f_\pi; the current quark masses are fitted to m_\pi and m_K. The obtained electromagnetic form factors are in good agreement with the data. Also the weak K_{l3} decay and the radiative and strong decays of the vector mesons agree reasonably well with the data. Finally, we indicate how processes such as \pi-\pi scattering can be described within this framework as well.
