Nonleptonic hyperon decay in the quark model.

TLDR: In this paper, the parity-violating and parity-conserving amplitudes of non-leptonic hyperon and tr decays are discussed in the nonrelativistic quark model and the SU(6) theory, where the pole diagram for quark is considered.

Abstract: Nonleptonic hyperon and tr decays are discussed in the nonrelativistic quark model and the SU(6) theory, where we consider the pole diagram for quark. the four-body weak current­ current interaction J1 2 J3 1 and the meson exchange interaction_ We assume two models, and can explain the experiments for parity-violating and parity-conserving amplitudes of nonleptonic hyperon decays. In particular the L1I = 1/2 rule is derived, though the weak current-current interaction J1 2 J3 1 does not satisfy £11 = 1/2. As to the decay of tr two models predict the different ratio of r(SJ~A+K) and r(SJ~S+ll). One is consistent with experiment, the other forbids SJ~A+K.
