Abstract
In order to explain the phenomena of CP violation using the current-current interaction, several authors, including one of the present authors (M. K.), have introduced a neutral current in the form of the universal V-A current-current interaction. Then there appears a part in the Hamiltonian to produce the ΔS=2 transition in first order. In this article, we treat the nonleptonic hyperon decays with ΔS=2, Ξ→Nπ, and obtain decay rates and asymmetry parameters using both the above interaction and the second order effect of the usual current-current interaction. In the latter case use is made of the baryon pole model. Comparison between the two calculations shows that there is a possibility of a considerable change in the asymmetry parameters of the decays Ξ→Nπ in the presence of the above-mentioned neutral current.
