In this paper we discuss Nambu-Jona-Lasinio model as a classical model for
dynamical mass generation and symmetry breaking. In addition we discuss the
possible supersymmetric extensions of this model resulting from interaction
terms with four chiral superfields that may be regarded as a supersymmetric
generalization of the four-fermion interactions of the Nambu-Jona-Lasinio
model. A four-superfield interaction terms can be constructed as either
dimension 6 or dimension 5 operators. Through analyzing solutions to the gap
equations, we discuss the dynamical generation of superfield Dirac mass,
including a supersymmetry breaking part. A dynamical symmetry breaking
generally goes along with the dynamical mass generation, for which a
bi-superfield condensate is responsible.
