Radiative decay into $\gamma$-baryon decuplet of dynamically generated resonances

TL;DR

This paper investigates the radiative decay processes of dynamically generated SU(3) decuplet resonances into gamma and baryons, highlighting the variability in decay widths and the potential for experimental insights into their nature.

Contribution

It provides a theoretical analysis of radiative decay widths of vector meson-baryon dynamically generated resonances, emphasizing differences across charge states.

Findings

Partial decay widths vary significantly among resonances.

Charge states of the same resonance exhibit different decay widths.

Experimental data could clarify the nature of these resonances.

Abstract

We study the radiative decay into $\gamma$ and a baryon of the SU(3) decuplet of ten resonances that are dynamically generated from the interaction of vector mesons with baryons of the decuplet. 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.
