Radiative decay into {gamma}-baryon of dynamically generated resonances from the vector-baryon interaction

We study the radiative decay into {gamma} and a baryon of the SU(3) octet and decuplet of nine and ten resonances that are dynamically generated from the interaction of vector mesons with baryons of the octet and the decuplet respectively. We obtain quite different partial decay widths for the various resonances, and for different charge states of the same resonance, suggesting that the experimental investigation of these radiative decays should bring much information on the nature of these resonances. For the case of baryons of the octet we determine the helicity amplitudes and compare them with experimental data when available.

Vector baryon interaction and dynamically generated resonances

The formalism for the interaction of vector mesons with baryons within the local hidden gauge formalism is presented and it is shown to lead to a large amount of dynamically generated baryonic resonances, many of which can be associated to known states, while others represent predictions for new resonances.
