Recent soft-core baryon–baryon interactions Original Research Article

We present recent results obtained with the extended soft-core (ESC) interactions. This ESC-model, henceforth called ESC03, describes nucleon–nucleon (NN), hyperon–nucleon (YN), and hyperon–hyperon (YY), in a unified manner using (broken) SUf(3)-symmetry. Novel ingredients are the inclusion of (i) the axial-vector meson potentials, (ii) a zero in the scalar-meson form-factors. With these innovations, it proved possible for the first time to keep the parameters of the model closely to the predictions of the View the MathML source quark-pair-creation model (QPC). This is the case for the meson–baryon coupling constants and F/(F+D)-ratioʹs as well. Also, the YN and YY results for this model are rather excellent.
