Baryon–Baryon and Meson–Baryon Potentials with QCD-Based Short-Range Cores

Abstract

A unified potential model of baryon–baryon and meson–baryon interactions at low energies is proposed. In this model, the short-range cores which simulate recent lattice QCD calculations are introduced. In baryon–baryon sector, our potentials give a very good agreement with NN and YN scattering data and have very similar behavior to those from the lattice QCD calculations. The πN and KN interactions are also well described in our model.
