The Kaon Form Factor in the Light-Cone Quark Model
Bo-Wen Xiao, Xin Qian, Bo-Qiang Ma
The electromagnetic form factor of the kaon meson is calculated in the light-cone formalism of the relativistic constituent quark model. The calculated form factor is consist…
High Precision Test of QCD at Beijing Electron Positron Collider
Bo-Qiang Ma
The generalized Crewther relation relates the cross section ratio in annihilation with the Bjorken sum rule or the Gr…
Parton Sum Rules and Nucleon Structure Functions
Bo-Qiang Ma
A brief summary on the Wigner rotation effect in the understanding of the proton spin ``crisis" related with the Ellis-Jaffe sum rule violation, and on the proton-neutron isospin s…
Non-perturbative effect in the nucleon structure function and the Gottfried sum
Jian-Jun Yang, Bo-Qiang Ma, Guang-Lie Li
We investigate the non-perturbative effect in the nucleon structure function and the Gottfried sum by using a non-perturbative quark propagator with lowest dimensional condensate c…
