Hyperon and. cap omega. /sup -/ nonleptonic weak decays
Journal Article

· Phys. Rev., D; (United States)
Nonleptonic hyperon and ..cap omega../sup -/ decays are analyzed in the framework of the Weinberg-Salam model of weak interactions. Various effective weak nonleptonic Hamiltonians are tested with and without quantum-chromodynamic corrections, including extensive variations of all the parameters in question. The influence of quark models is also investigated using both the MIT bag model and the harmonic-oscillator model. Various dynamical assumptions connected with particular selections of current-commutator and pole terms are also considered. Irrespective of all variations and uncertainties, it seems that orders of magnitude and relative signs for various amplitudes are always correctly reproduced.
