Nonleptonic Weak Interactions in the Delta and Hypernuclear Sectors
Abstract
Two areas of nonleptonic weak interactions are examined: parityviolation in nucleonnucleon interactions including Delta excitations, and strangenesschanging hypernuclear decay processes. In both cases we utilize SU(6)_{w} based quark model pictures to describe the weak hadronic physics. In the first part of this dissertation we develop an effective parityviolating Hamiltonian for the weak interactions of Delta's with hadrons and mesons. We evaluate weak parityviolating DeltaDelta meson and Deltanucleonmeson vertices for pi, rho, and omega mesons, thus extending previous work involving only nucleons and mesons. The second part of this dissertation presents the results of calculations for several observables involving the decay of hypernuclei. We examine the model dependence of these observables by considering several variations of the model and its parameters.
