The nucleon spin structure in a simple quark model
Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang
We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional structure, different admixtures in t…

The Nuclear Effect Induced by Additional Parton Evolution and Recombination in Nuclear Environment
Jian-Jun Yang, Guang-Lie Li
The relationship between the parton transverse momentum and longitudinal momentum, which is obtained by analysing the hadron tensor in the deep inelastic scattering (DIS) process,…

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…
