Generalized parton distribution function (E{sup u}+E{sup d})(x,{xi},t) of the nucleon in the chiral quark soliton model
Abstract
The unpolarized spinflip isoscalar generalized parton distribution function (E{sup u}+E{sup d})(x,{xi},t) is studied in the largeN{sub c} limit at a low normalization point in the framework of the chiral quarksoliton model. This is the first study of generalized parton distribution functions in this model, which appear only at the subleading order in the largeN{sub c} limit. Particular emphasis is put therefore on the demonstration of the theoretical consistency of the approach. The forward limit of (E{sup u}+E{sup d})(x,{xi},t) of which only the first momentthe anomalous isoscalar magnetic moment of the nucleonis known phenomenologically, is computed numerically. Observables sensitive to (E{sup u}+E{sup d})(x,{xi},t) are discussed.
