Abstract

We study nucleon structure functions within the bosonized version of the Nambu-Jona-Lasinio (NJL) model in which the nucleon emerges as the soliton in the chiral field. Upon boosting to the infinite momentum frame and performing the q²-evolution in the context of the Gottfried sum rule for electron nucleon scattering we determine the intrinsic scale μ² of the NJL chiral soliton. We also compute the leading twist contributions of the polarized structure functions g₁ and g₂. We compare these model predictions with experiment by evolving them from μ² to the scale where the data are taken. Analogously we analyze the chiral-odd structure functions h_T and h_L. Finally we generalize the treatment to flavor SU(3).
