| Abstract | Using the recent Hara’s-theorem-confirming measurement of the Ξ0 → Λγ asymmetry as an input, we reanalyse nonleptonic and weak radiative hyperon decays in a single symmetry-based framework. In this framework the old S:P problem of nonleptonic decays is automatically resolved when the most important features of weak radiative decays are taken into account. Experimental data require that symmetry between the two types of hyperon decays be imposed at the level of currents, not fields. Previously established connections between hyperon decays and nuclear parity violation imply that the conflict, originally suggested by weak radiative decays, has to surface somewhere. With Hara’s theorem satisfied, it follows that either the universality of the (vector) currentfield identity or the generally accepted approach to nuclear parity violation must be incorrect. |
