英文摘要:
By introducing auxiliary fields, which by their quantum numbers vanish in perturbation theory, we relate the dynamical perturbation theory of Pagels and Stokar and a successful gauged nonlocal constituent quark model to a U(N) gauge theory and to QCD. This sheds Light on the duality between quark models and resonance models. We then derive the effective action;in the loop expansion without dropping cubic and quartic gluon couplings.
