Dynamical P-parity Breaking in Effective Quark Model
A. A. Andrianov, V. A. Andrianov, V. L. Yudichev
Abstract
Fermion models with selfinteraction including derivatives of fields are investigated in the strong coupling regime. The existence of three phases is established in the two channel model near tricritical point. The special phase of dynamical P-parity breaking is found.
