Nucleon structure functions in the three-flavor NJL soliton model

We study the relevance of strange degrees of freedom for nucleon structure functions, For this purpose we employ the three-flavor generalization of th e collective quantization approach to the chiral soliton of the bosonized N ambu-Jona-Lasinio model. Contrary to many other soliton models the hadronic tensor is tractable in this model. By applying the Bjorken limit to the ha dronic tensor we extract the leading twist contributions to the nucleon str ucture functions at the Low energy scale at which the model is assumed to a pproximate QCD. After transforming to the infinite momentum frame and perfo rming the DGLAP evolution program to these structure functions we compare w ith available data for deep inelastic electron-nucleon scattering.
