A systematic study of three-baryon forces based on the SU(3) model

We discuss the systematic bahavior of three-baryon forces through a generalization of the three-nucleon force based on the SU(3) model. We consider not only the two-pion exhange mechanism but also heavy-meson exchange machanisms, including K-meson. In addition, we apply the three-baryon forces to determine the equation of state of high-density baryonic matter like neutron-star matter.
