Title: Description of intermediate- and short-range NN nuclear force within a covariant effective field theory

Abstract

The present paper is aimed to developing an effective field theory in the GeV region to describe consistently both elastic and inelastic NN scattering in a fully covariant way. In this development we employ our novel s-channel mechanism of NN interaction at intermediate and short ranges assuming a formation of the six-quark bag dressed with basic meson fields such as {pi}, {sigma}, {rho}, and {omega} in the intermediate state. The peripheral part of the interaction is governed by t-channel one- and two-pion exchanges described fairly well by chiral perturbation theory. The {sigma}-meson dressing should be especially important for the stabilization of the bag due to a high coupling constant of the {sigma}-meson with the bag and also a strong interaction between the {sigma}-field and space symmetric quark core |s{sup 6}[6]>. This stabilization of the intermediate dressed bag (which shifts the mass of the bag downward to NN threshold) will be crucially important for the description of {pi}, 2{pi}, {rho}, and {omega}-meson production in NN collisions, and, in particular, for the correct description of {pi} {sup 0} production near threshold. So that, we expect that the results of the present work will lead to a deeper understanding the short- and intermediate-rangemore » nuclear forces and internucleon correlations in nuclei.« less
