Abstract
The dynamical structure of the nucleon is studied in the chiral versio n of the chromodielectric model. The color-dielectric field and the me son clouds are described by hedgehog coherent states. Standard project ion techniques are used to construct zero-linear-momentum eigenstates with the nucleon quantum numbers of angular momentum and isospin. Both the unpolarized and the polarized quark distribution functions are co mputed. Results are in good agreement with the data and a noticeable i mprovement with respect to the predictions of the non-chiral model is observed.
