The contribution of the final-state interaction to the differential cross-section of deuteron photodisintegration at laboratory photon energies below 50 MeV is analyzed in the framework of Bethe–Salpeter formalism with a phenomenological rankone separable interaction. The approximations made are the neglect of two-body exchange currents, negative-energy components of the bound-state vertex func...

Final state hyperon-nucleon interaction in strangeness photoproduction of the deuteron is investigated making use of the covariant reaction formalism and the P –matrix approach to the YN system. Remarkably simple analytical expression for the amplitude is obtained. Pronounced effects due to final state interaction are predicted including the manifestation of the 2.13 GeV resonance.
