Fermion models with selfinteractions including derivatives of fields are investigated in the strong coupling regime when several coupling constants are matched to thier critical values. The existence of three phases with different correlation lengths is established in the scalar channel model near tricritical point. The special phase of dynamical P-parity breaking is found. The mass spectra of composite scalar and pseudoscalar bosons are obtained in the large-log approximation.
