Spin-orbit force in a quark model based nucleon-nucleon potential
Physical Review C, 1995•APS
The spin-orbit interaction coming from the scalar meson-exchange potential between quarks
is included in a quark cluster model for the nucleon-nucleon interaction. Its influence on the
triplet P-wave scattering phase shifts and on the baryon spectrum is analyzed. We require
that the deuteron binding energy is simultaneously reproduced. Our results indicate that a
considerable part of the nucleon-nucleon spin-orbit force can be explained by gluon and
sigma exchange between quarks while improving the description of the excited baryon …

Abstract
The spin-orbit interaction coming from the scalar meson-exchange potential between quarks is included in a quark cluster model for the nucleon-nucleon interaction. Its influence on the triplet P-wave scattering phase shifts and on the baryon spectrum is analyzed. We require that the deuteron binding energy is simultaneously reproduced. Our results indicate that a considerable part of the nucleon-nucleon spin-orbit force can be explained by gluon and sigma exchange between quarks while improving the description of the excited baryon spectrum.
