Non-zero transversity distribution of the pion in a quark-spectator-antiquark model
Zhun Lu, Bo-Qiang Ma
We calculate the non-zero (naïve) T-odd transverse momentum dependent transversity distribution $h_1^{\perp}(x,\kp^2)$ of the pion in a quark-spectator-antiquark model. The final-s…
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…
Collins Effect in Single Spin Asymmetries of the Process
Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang
We investigate the Collins effect in single spin asymmetries (SSAs) of the process, by taking into account the transverse momentum dependence of the microsco…
The 35-plet Baryons from Chiral Soliton Models
Bin Wu, Bo-Qiang Ma
We investigate the 35-plet baryons from the chiral soliton models. We find that the coupling constant for the decay of 35-plet baryons with spin 3/2 to the decuplet baryons is surp…
Particle-Antiparticle Asymmetries of Production in Hadron-Nucleon Collisions
Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang
The particle-antiparticle asymmetries of production in 250 GeV/c , , and --nucleon collisions are studied with two model parametrizations of quark to …
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…
