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 (Q2) dependence is perturbative. These predictions are compared with experimental measurements of the F3 structure function in neutrino nucleon deep inelastic scattering.
