Nucleon quasi-parton distribution functions within the chiral quark soliton model — •Hyeon-Dong Son, Asli Tandogan-Kunkel, and Maxim V. Polyakov — Institut für Theoretische Physik II Fakultät für Physik und Astronomie Ruhr-Universität Bochum 44780 Bochum Deutschland

Quasi-Parton Distribution Functions(qPDFs), recently suggested by X. Ji, are of great importance as they open access to usual parton distribution functions in the lattice simulation of the QCD. It is meaningful to achieve a reliable calculation of them from a QCD-effective approach at low energy regime to provide a better insight. In this context, we present our recent studies on the nucleon qPDFs within the framework of the chiral quark-soliton model. We describe the evolution of the qPDFs as the nucleon velocity approaches to the light-like limit v→1 and discuss the relevant sum rules as well.
