Nucleon sea in the effective chiral quark model
Yong Ding, Rong-Guang Xu, Bo-Qiang Ma
The asymmetries of both light-flavor antiquark and strange-antistrange distributions of the nucleon sea are considered with more details i…

Sigma Meson Cloud and Proton's Light Flavor Sea Quarks
Feng Huang, Rong-Guang Xu, Bo-Qiang Ma
We take into account the sigma meson cloud effect in the meson cloud model to calculate the distributions of light flavor sea quarks in the proton. Our calculation gives a better d…

Effect of Asymmetric Strange-Antistrange Sea to the NuTeV Anomaly
Yong Ding, Rong-Guang Xu, Bo-Qiang Ma
We calculate the strange quark and antiquark distributions of the nucleon by using the effective chiral quark model, and find that the strange-antistrange asymmetry can bring a con…
