Three-body nuclear forces are essential for explaining the properties of light nuclei with a nucleon number greater than three. Building on insights from physics, we extract form quark three-body interactions and demonstrate that these terms crucial extending model fit meson spectrum to include baryons using same parameter set. We then discuss implications our findings exotic configurations involving more three quarks, such as $T_{cc}$ $\chi_{c1}(3872)$. find provide additional repulsion order 10 MeV compact both This result, combined previous calculations, strongly suggests tetraquark states molecular rather states.
