Title: Baryon-baryon scattering in a one-boson-exchange-potential approach. I. Nucleon-nucleon scattering

Abstract

From a combined analysis of nucleon-nucleon and hyperon-nucleon scattering with a one-boson-exchange-potential-model the NN results are presented. The model consists of local potentials due to exchanges of members of the pseudoscalar and vector meson nonets and the scalar meson epsilon taken as a unitary singlet. Effects of the large widths of the epsilon and rho meson are included. The Schrodinger equation is solved in configuration space with phenomenological hard-core potentials at short distances. The coupling constants and hard core-radii are determined in a fit using the NN phase-shift analysis of the Livermore group up to 330 MeV laboratory kinetic energy and the low-energy parameters. The NN phase shifts are described well with chi$sup 2$/data = 2.4 as good as the purely phenomenological potentials and good values are obtained for the scattering length effective ranges, and deuteron parameters.
