  We discuss an approach for accessing bound state properties, like mass and
decay width, of a theory within the functional renormalisation group approach.
An important cornerstone is the dynamical hadronization technique for resonant
interaction channels. The general framework is exemplified and put to work
within the two-flavour quark-meson model. This model provides a low-energy
description of the dynamics of two-flavour QCD with quark and hadronic degrees
of freedom. We compare explicitly the respective results for correlation
functions and observables with first principle QCD results in a quantitative
manner. This allows us to estimate the validity range of low energy effective
models. We also present first results for pole masses and decay widths. Next
steps involving real-time formulations of the functional renormalisation group
are discussed.
