Abstract
We obtain in the leading order of 1/N expansion, the fermion-fermion e ffective potential for the three-dimensional model of (N) massless Dir ac spinors with a general current and scalar quadrilinear self-interac tion. Analyzing the Schrodinger equation in the presence of the nonrel ativistic limit of this potential, we show that this system presents a fermion-fermion bound state.
