Proton spin in a light-cone chiral quark model
Xinyu Zhang, Bo-Qiang Ma
We discuss the spin structure of the proton in a light-cone treatment of the chiral quark model. Based on the fact that the quark helicity () measured in polarized deep inelast…

Light flavor asymmetry of nucleon sea
Huiying Song, Xinyu Zhang, Bo-Qiang Ma
The light flavor antiquark distributions of the nucleon sea are calculated in the effective chiral quark model and compared with experimental results. The contributions of the flav…

Isospin Symmetry Breaking in the Chiral Quark Model
Huiying Song, Xinyu Zhang, Bo-Qiang Ma
We discuss the isospin symmetry breaking (ISB) of the valence- and sea-quark distributions between the proton and the neutron in the framework of the chiral quark model. We assume…
