Calculating hadron properties from dynamical hadronization in the Functional Renormalisation Group

Abstract

We report on a functional renormalisation group approach to bound state properties similar to the Dyson-Schwinger–Bethe-Salpether approach. The current approach is set-up for the two-flavour quark-meson model for an illustration of the basic properties. This allows us to access the pion and sigma poles and decay properties. First numerical results are presented and evaluated. We also discuss the next steps.
