Strangeness Dependence in Radiative Hyperon Decay Amplitudes
T. Haberichter, H. Reinhardt, N. N. Scoccola, H. Weigel
Abstract
The radiative decays of the (3/2)+ baryons are studied in the three flavor generalization of the Skyrme model. The kaon fields are treated in the slow rotator approach which properly accounts for the observed deviations from the U-spin relations for the hyperon magnetic moments. This makes possible a critical discussion of the U-spin selection rules for the radiative hyperon decays. The variation of the decay widths with strangeness is studied and a comparison with other treatments of the SU(3) Skyrme model is performed in order to analyze the effects of flavor symmetry breaking.
