To the nature of intermediate- and short-range nucleon-nucleon interaction

Abstract

Instead of the Yukawa mechanism for intermediate- and short-range interaction some new approach based on formation of the symmetric six-quark bag in the state $|(0s{)}^6[6{]}_X,L=0>$ dressed due to strong coupling to $\pi$, $\sigma$ and $\rho$ fields are suggested. This new mechanism offers both a strong intermediate-range attraction which replaces the effective $\sigma$-exchange (or excitation of two isobars in the intermediate state) in traditional force models and also short-range repulsion. Simple illustrative model is developed which demonstrates clearly how well the suggested new mechanism can reproduce $NN$ data.
