Abstract：
Constituent quark models based on two-body potentials systematically overpredict the mass of Δ_D35(1930). A possible solution to this problem comes out from the application of a schematic hybrid model, containing three-quark as well as meson-baryon components, to the light-quark baryon spectrum. The Δ_D35(1930) and its partners Δ_D33(1940) and Δ_S31(1900) are found to contain a significant ρΔ component. Then, through the use of the hidden gauge formalism, it is shown that these resonances can be dynamically generated from the ρ-Δ interaction. In particular Δ_D35(1930) can be interpreted as being essentially a ρΔ bound state. This interpretation suggests that the inclusion of ρΔ as an effective inelastic channel in data analyses could improve the extraction and identification of the resonance.
