Scientific paper
Based on a Lagrangian with a coupling of two gluons to J^pi=0^+ (the quantum numbers of the vacuum) which decay to q-qbar pairs, a model is presented, in which hadrons couple directly to the absolute vacuum of fluctuating gluon fields. By self-consistency requirements the confinement potential as well as hadron densities and masses are obtained, which are in good agreement with experimental data on scalar and vector mesons. In comparison with potential models additional states are predicted, which can explain the large continuum of scalar states in the low mass spectrum and new states in the charm region. The present model is consistent with the concept, that the hadron masses can be understood by binding effects of the quarks.
