Radial excited states of the nucleon in quark models with dynamical confinement
M. Fiolhais, P. Alberto, B. Golli, S. Sirca
Abstract
The Roper state is described in the framework of the chiral chromodielectric model as a single quark excitation in self-consistent meson potentials. The interplay between quark and meson excitations is discussed and we emphasise the role of non-quark degrees of freedom in the electroproduction of nucleon excitations.
