Abstract

We study the short-distance part of the intrinsic three-nucleon interaction in a constituent quark model with color-spin interaction. For that purpose, we first calculate the transformation coefficient between the tribaryon configuration and their corresponding three-baryon basis. Using a formula for the intrinsic three-body interaction in terms of a tribaryon configuration, we find that after subtracting the corresponding two-baryon contributions, the intrinsic three-body interaction vanishes in flavor SU(3) symmetric limit for all quantum numbers for the three nucleon states. We further find that the intrinsic three-body interaction also vanishes for flavor-spin type of quark interaction.
