Abstract

Nucleon structure functions are studied within the chiral soliton approach to the bosonized Nambu-Jona-Lasinio model. The valence quark approximation is employed which is justified for moderate constituent quark masses (∼ 400 MeV) as the contribution of the valence quark level dominates the predictions of nucleon properties. As examples the unpolarized structure functions for the νp and ν̄p scattering and the structure functions entering the Gottfried sum rule are discussed. For the latter the model prediction is found to reasonably well agree with a corresponding low-scale parametrization of the empirical data.
