Radiative Decays of Hyperons in the Skyrme Model: E2/M1 Transitions

Abstract

We study the radiative decays of $J^{\pi }={\frac{3}{2}}^{+}$ baryons in the framework of the SU(3) collective approach to the Skyrme model. We present the predictions for the decay widths and the corresponding $E2/M1$ ratios. We find that all considered ratios are negative and of the order of a few percent only. We discuss the effects of flavor symmetry breaking and compare our results to those obtained in related models.
