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 Îγand Î^* \to Îγ. 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.
