Add to ORKGThe investigation is devoted to the construction of the field model allowing the accurate solutions and limit transfer of the truncation parameter to the infinity. The accurate expressions for wave founctions of the vacuum, one-partial and two-partial states and their spectra have been obtained in the model of the contact four-fermion interaction "current x current". The breach of the initial symmetry in one of three studied Hamiltonian realizations has been discovered, and the wave function and equation for the energy of the corresponding Goldstone mode have been found. The reduction of the Fadeev equation system for three-partial wave functions has been specified. The procedure for prevention of the divergence in this "non-...
