Unified description of N N and Y N interaction in the SU6 quark model

Abstract

A simultaneous description of the N N and Y N interactions is possible in the resonating-group formulation of the spin-flavor SU 6 quark model, which incorporates the full Fermi-Breit interaction with explicit quark-mass dependence and the minimum meson-exchange potentials of scalar and pseudo-scalar meson nonets directly coupled to quarks. With a small number of parameters, satisfactory agreement with experiment is obtained for the N N properties and the total and differential cross sections of the Λ N and Σ N systems. The H-particle binding energy and Ξ - p total cross sections are also discussed.
