Description
Upper bounds on rate differences between particle and antiparticle decays of hyperons are estimated in the standard six-quark model. For each of Λ0→pπ-, Λ0→nπ0, Σ+→nπ+, Σ+→pπ0 fractional rate differences of order 10-6 are found whereas for Σ-→nπ-, Ψ-→Λπ-, and Ψ0→Λπ0 none is expected. Some other tests of CP conservation in hyperon decays relevant to left-right symmetric models are pointed out
