Dyson-Schwinger studies of meson masses and decay constants

The masses and decay constants of the light mesons are studied within a ladder-rainbow truncation of the set of Dyson-Schwinger equations using a model 2-point gluon function. The one phenomenological parameter and two current quark masses are fitted to reproduce $f_\pi$, $m_\pi$ and $m_K$. Our results for $f_K$, and for the vector mesons $\rho$, $\phi$, and $K^\star$ are in good agreement with the experimental values.
