Polynomiality of helicity off-forward distribution functions in the chiral quark-soliton model
arXiv:hep-ph/0303166 · doi:10.1103/PhysRevD.67.114022
Abstract
The polynomiality condition -- i.e. the property that Mellin moments of off-forward distribution functions are even polynomials in the skewedness parameter -- is a demanding check of consistency for model approaches. We demonstrate that the helicity off-forward distribution functions in the chiral quark-soliton model satisfy the polynomiality property. The proof contributes to the demonstration that the description of off-forward distribution functions in the model is consistent.
