Electromagnetic, weak, and strong interactions of light mesons
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 fπ; the current quark masses are fitted to mπ and mK. The obtained electromagnetic form factors are in good agreement with the data. Also the weak Kl3 decay and the radiative and strong decays of the vector mesons agree reasonably well with the data. Finally, we indicate how processes such as π-π scattering can be described within this framework as well.
