A dressed bag model study of the final-state $N\Delta$ interaction in photoproduction processes off the deuteron

Abstract

The impact of the short-range $N\Delta$ interaction on the pion photoproduction processes off the deuteron in the $\Delta$-resonance region is studied in the framework of recently proposed dressed-bag model. A common dressing procedure for bare three- and six-quark states is used to describe both the pion decay widths of baryon resonances and the effective $NN$ (or $N\Delta$) interaction at short ranges related to the inner dressed-bag states. It is shown that the effect of short-range $N\Delta$ interaction for the forward-angle ${\pi }^{\mathrm{o}}$ photoproduction off the deuteron cannot be neglected. The prospects for further development of the model to describe the short-range $NN$ (or $N\Delta$) correlations in the lightest nuclei are discussed.
