摘要
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* --> Delta gamma and Delta* --> 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. (C) 1998 Elsevier Science B.V.
