Coupling constant singularities of the nucleon-nucleon interaction (II)

G. Hazak, A. Gersten

Research output: Contribution to journalArticlepeer-review


In a previous paper we presented a formalism which enables an exact analysis of the location of coupling constant singular points for approximate Bethe-Salpeter equations with nonlocal pseudopotentials. In the present work the formalism is applied to the interaction of two spin- 1 2 particles exchanging vector or scalar mesons. (The electromagnetic interaction is a special case.) Analytic expressions for the singular points are obtained. These expressions are independent of the masses and energies of the particles. The physical significance of the singular points is discussed.
