    "abstract": "The masses and decay constants of the light mesons are studied within a\nladder-rainbow truncation of the set of Dyson-Schwinger equations using a model\n2-point gluon function. The one phenomenological parameter and two current\nquark masses are fitted to reproduce $f_\\pi$, $m_\\pi$ and $m_K$. Our results\nfor $f_K$, and for the vector mesons $\\rho$, $\\phi$, and $K^\\star$ are in good\nagreement with the experimental values.",
