    "abstract": "We study the role of quark-quark correlation in the baryon structure and, in\nparticular, the hyperon non-leptonic weak decay, which is sensitive to the\ncorrelation between quarks in the spin-0 channel. We rigorously solve\nnon-relativistic three-body problem for SU(3) ground state baryons to take into\naccount the quark-pair correlation explicitly. With the suitable attraction in\nthe spin-0 channel, resulting static baryon properties as well as the parity\nconserving weak decay amplitudes agree with the experimental values. Special\nemphasis is placed also on the effect of the SU(6) spin-flavor symmetry\nbreaking on the baryon structure. Although the SU(6) breaking effects on the\nlocal behavior of the quark wave functions are considerable due to the spin-0\nattraction, the calculated magnetic moments are almost the same as the naive\nSU(6) expectations.",
