A Novel Approach to Nonleptonic Weak Hyperon Decays.

摘要

A phenomenological theory of nonleptonic hyperon decays is proposed which does not rely on octet dominance and on R or RP invariance. Postulating SU3 symmetry and a certain space-time behavior, a minimal HW is uniquely obtained. All S- and P-wave amplitudes are computed and expressed in terms of five parameters. Experimentally correct relations are deduced. (Author)
