W. Pfister, EXACT-SOLUTIONS OF GENERALIZED 3-PARTICLE BARGMANN-WIGNER EQUATIONS IN THE STRONG-COUPLING LIMIT, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 107(9), 1994, pp. 1523-1541
Starting from a non-linear isospinor-spinor field equation, generalize
d three-particle Bargmann-Wigner equations are derived. In the strong-
coupling limit, exact solutions of these equations are obtained. This
will be demonstrated for a special class of J = 1/2 bound-state soluti
ons which are calculated in the rest frame of the three-particle bound
state.
