We study a previously introduced bi-local gauge invariant reformulation of two-dimensional QCD, called 2d hadron dynamics. The baryon arises as a topological soliton in hadron dynamics. We derive an interacting parton model from the soliton model, thus reconciling these two seemingly different points of view. The valence quark model is obtained as a variational approximation to hadron dynamics. A...
In this paper we study a 1+1 dimensional relativistic parton model for the structure of baryons. The quarks and anti-quarks interact through a linear potential. We obtain an analytic formula for the isospin averaged valence quark distribution in the chiral and large N c limits. The leading 1N c and non-zero current quark mass corrections are estimated. Then we extend this model to...
