Excitation of non-quark degrees of freedom in N*
B. Golli, P. Alberto, M. Fiolhais
We study the contribution of glueball and sigma-meson degrees of freedom to nucleon excited states in the framework of a chiral version of the chromodielectric model. We have found…
Small quark stars in the chromodielectric model
M. Malheiro, E. O. Azevedo, L. G. Nuss +2
Equations of state for strange quark matter in beta equilibrium at high densities are used to investigate the structure (mass and radius) of compact objects. The chromodielectric m…
Pseudospin symmetry as a relativistic dynamical symmetry in the nucleus
P. Alberto, M. Malheiro, A. Delfino +2
Pseudospin symmetry in nuclei is investigated by solving the Dirac equation with Woods-Saxon scalar and vector radial potentials, and studying the correlation of the energy splitti…
N^* electroproduction amplitudes in a model with dynamical confinement
P. Alberto, M. Fiolhais, B. Golli +1
The Roper resonance is described in a chiral version of the chromodielectric model as a cluster of three quarks in radial-orbital configuration (1s)(2s), surrounded by …
