We do this by considering unquenching effects in the form of hadronic resonance contributions, notably pion exchange, and by the inclusion of the dominant gluon self-interactions to the quark-gluon vertex. Thus we make steps towards an ab initio description of light mesons by functional methods.6 pages,1 figure.
