A New Triangle Relation for Nonleptonic Hyperon Decay Amplitudes as a Consequence of the Octet Spurion and the<i>R</i>Symmetry

Abstract

A triangle relation TΛ=2TΞ-+√3TΣ0 is obtained for the nonleptonic decay amplitudes of Λ→p+π-, Σ+→p+π0 and Ξ-→Λ+π-. This relation is shown to be in excellent agreement with the experiment especially when γΣ+→p+π0>0. The assumptions are the octet spurion hypothesis and the R symmetry.
