Strange-antistrange and charm-anticharm asymmetries of pion in 't Hooft model
Mingliang Zhu, Siwei Hu, Yu Jia +2
As a sequel of our preceding work [S. Hu et al., Phys. Rev. D 108 (2023) 9, 094040], we investigate the strange-antistrange and charm-anticharm asymmetries in the parton distributi…

Light quark mass dependence of nucleon mass to two-loop order
Long-Bin Chen, Siwei Hu, Yu Jia +1
We investigate the nucleon self energy through the sixth chiral order in the covariant chiral perturbation theory (PT) in the single baryon sector. The validity of the e…

Next-to-leading-order QCD corrections to nucleon Dirac form factors
Long-Bin Chen, Wen Chen, Feng Feng +2
The leading-order perturbative QCD (pQCD) predictions to nucleon electromagnetic form factors were first made in late 70s. In this Letter for the first time we accomplish the calcu…
