Abstract:

The weak radiative decays of 1/2⁺ baryons are analyzed by considering the decay B →B'+ γ as a process S+B →B'+ γ and assuming besides CP-invariance, (i) non-exoticity of the intermediate states and (ii) the s-u channel symmetry of the weak Hamiltonian. Decay rates and asymmetry parameters of charmed and uncharmed decays are calculated. We propose measurement of asymmetries for Ξ^- →Σ^- γ and Ξ⁰ →Σ⁰ γ in order to elucidate the structure of weak nonleptonic Hamiltonian.
