Photoproduction of Excited Baryons in the 1/Nc Expansion of QCD
We present results for the photoproduction helicity amplitudes of excited baryons obtained in the context of the 1 /Nc expansion of QCD. The results show that, in order to get a satisfactory description of the observed photoproduction amplitudes, the sub-leading corrections in 1/Nc are important. We...
