Abstract

The impact of the short-range NΔN\Delta interaction on the pion photoproduction processes off the deuteron in the Δ\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 NNNN (or NΔN\Delta) interaction at short ranges related to the inner dressed-bag states. It is shown that the effect of short-range NΔN\Delta interaction for the forward-angle πo\pi^\mathrm{o} photoproduction off the deuteron cannot be neglected. The prospects for further development of the model to describe the short-range NNNN (or NΔN\Delta) correlations in the lightest nuclei are discussed.
