Query: Effective Fermion Models in Symmetry-Breaking Phase and Quantum
  Chromodynamics   In our lecture we discuss the fermion models with quasilocal interaction
implemented by derivatives and a momentum cutoff as substitutes of QCD at low
energies. They are investigated in the strong coupling regime when several
coupling constants are matched to their critical values. It is found that
around polycritical points there appear a number of resonances with the same
quantum numbers. Respectively the particular change of enviroment caused by
gluon condensate results in the mass splitting independent of the cutoff. Such
models are supposed to be an essential ingredient in the description of quark
matter at high baryon densities.
