Abstract

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 fπ, mπ and mK. Our results for fK, and for the vector mesons ρ, ϕ, and K are in good agreement with the experimental values.
