✦ Synopsis

The projection of the tbur-dimensional two-body Bethe-Salpeter equation at the lightfront hypersurface is discussed. Elimination of the relative time is performed using a quasi-potential expansion, which is shown to be equivalent to an infinite set of coupled equations for the Green's functions of the different light-front Fock-states.

with the interaction Lagrangian respectively given by, £~ = gs¢~¢lCr + gs¢~¢2a and £~ = gxT~IJcr, where q51, qS.) and a are the bosonic fields and tIJ is the fermion field in the Ynkawa model.
