Pion parton distribution functions with the nonrelativistic constituent quark model
Qian Wu, Chengdong Han, Di Qing +4
We calculate the valence quark distribution functions of the meson using the non-relativistic chiral constituent quark model. The wave function is obtained by solving the t…
Understanding penta quark with various quark models
Jialun Ping, Di Qing, Fan Wang +1
The pentaquark state recently discovered has been studied with three quark models which either fit the nucleon spin structure or the scattering. A minimum mass of 1620 M…
Is nucleon spin structure inconsistent with constituent quark model?
Di Qing, Xiang-Song Chen, Fan Wang
A qualitative QCD analysis and a quantitative model calculation are given to show that the constituent quark model remains a good approximation even with the nucleon spin structure…
How does baryon magnetic moment relate to its spin structure
Xiang-Song Chen, Di Qing, Fan Wang
A model independent, field theoretical relation between baryon magnetic moment and its spin structure is derived and it is explained why constituent quark model is a good approxima…
Spin content of the nucleon in a valence and sea quark mixing model
Di Qing, Xiang-Song Chen, Fan Wang
A dynamical valence and sea quark mixing model is shown to fit the baryon ground state properties as well as the spin content of the nucleon. The relativistic correction and the $q…
