Abstract:

The approach which was proposed in a previous paper for treating the problem of bound states, is extended to the case where there are three kinds of basic particles; proton, neutron and Λ-particle. A general form of a four-Fermion interaction is obtained by assuming the full symmetry among the basic particles. Then, the particle-antiparticle two-body system is discussed in the vector coupling which contains a form factor, and the integral equations in the momentum representation are derived. Solutions are obtained in the special case of contact interaction.
