Decays of l=1 Baryons to Delta gamma

Abstract

Recently we considered the electromagnetic decays of the orbitally-excited SU(6) 70-plet baryons in large-N_c QCD, fitting to the helicity amplitudes measured in photoproduction experiments. Using the results of this analysis, we predict the helicity amplitudes for the decays N^* \to \Delta\gamma and \Delta^* \to \Delta\gamma. These decays can be studied at a number of new experimental facilities, and thus provide another nontrivial test of the lowest order large-N_c predictions.
