  Dynamical symmetry breaking and the formation of scalar condensates in the
SU(2)XU(1) Nambu-Jona-Lasinio model with two coupling constants has been
studied in the framework of the mean field approximation. The bosonization
procedures of the model are performed using the functional integration method.
The possibility of the spontaneous CP symmetry breaking in the model under
consideration has been shown. The mass spectrum of the bound states of
fermions, as well as the effective Lagrangian of interacting scalar and
pseudoscalar mesons are obtained.
