Proton Structure functions from large N QCD

I will describe work done in collaboration with S. G. Rajeev on
understanding the structure of the baryon in two dimensional QCD. The main
approximation is the limit of a large number of colors. The picture that
emerges allows us to derive a model of relativistic interacting quarks and
anti-quarks from an exact soliton description of the baryon. This will
then be used to propose a model for the non-perturbative momentum fraction
dependence of structure functions of the nucleon. The momentum transfer
(Q^{2}) dependence is perturbative. These predictions are compared with
experimental measurements of the F_{3} structure function in neutrino
nucleon deep inelastic scattering.
