Abstract

A momentum space OBEP for the two-nucleon scattering is constructed starting from a relativistically invariant quark model predictions of the meson-nucleon coupling constants. Taking a relativistic meson propagators and working in a quasipotential Blankenbecler-Sugar two-nucleon dynamics the relativistic invariance of the whole problem is maintained. The NN forces are generated by an exchange of the pi, eta, eta', delta, epsilon(600), rho, omega, and phi mesons. Phenomenological form factors for all meson-nucleon vertices and effective epsilon(600) and omega meson-nucleon couplings are utilized. The calculated NN phase shifts are in good agreement with the empirical data and with the predictions of the conventional Bonn OBEP model.
