Polynomiality of off-forward distribution functions in the chiral quark soliton model
Abstract
Mellin moments of off-forward distribution functions are, at t = 0, even polynomials of the skewedness parameter xi. It is proven that the unpolarized off-forward distribution functions in the chiral quark soliton model satisfy this so called polynomiality property. The proof is an important contribution to the demonstration that the description of off-forward distribution functions in the model is consistent.
