Baryon-baryon potentials in the flavor SU(3) limit from lattice QCD

Understand

We investigate baryon-baryon (BB) interactions in the flavor SU(3) symmetric world, by using the 3-flavor full QCD simulations.

• In the SU(3) limit, six independent two-baryon states exist for a given orbital angular momentum.
• We forcus on S-wave states and extract BB potentials using the method recently developed.
• We discuss the flavor dependence of the potentials, in particular, the strength of the repulsion at short distance.
