摘要：
I present a new perturbative approach to QCD based on the use of quark composites as fundamental variables. For the barions, a nonlinear change of variables is performed in Berezin integrals, whereby the barionic composites are assumed as new integration variables. For the mesons, auxiliary bosonic fields are introduced. The free actions of hadronic composites are constructed, and the perturbation theory based on these actions is outlined. The quarks are confined to zeroth order as a consequence of the spontaneous breaking of chiral invariance.
