Decays of l=1 Baryons to Delta gamma
Carl E. Carlson, Christopher D. Carone
Abstract
Recently we considered the electromagnetic decays of the orbitally-excited SU(6) 70-plet baryons in large-Nc 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* Δγand Δ* Δγ. These decays can be studied at a number of new experimental facilities, and thus provide another nontrivial test of the lowest order large-Nc predictions.
