| dc.description.abstract | We use the rho Delta interaction in the hidden gauge formalism to dynamically generate N-* and Delta(*) resonances. We show, through a comparison of the results from this analysis and from a quark model study with data, that the Delta(-)(5/2)(1930), Delta(-)(3/2)(1940), and Delta(-)(1/2)(1900) resonances can be assigned to rho Delta bound states. More precisely the Delta(-)(5/2)(1930) can be interpreted as a rho Delta bound state whereas the Delta(-)(3/2)(1940) and Delta(-)(1/2)(1900) may contain an important rho Delta component. This interpretation allows for a solution of a long-standing puzzle concerning the description of these resonances in constituent quark models. In addition we also obtain degenerate J(P)=1/2(-),3/2(-),5/2(-) N-* states but their assignment to experimental resonances is more uncertain. | |
