Transverse force tomography inside a proton from Basis Light-front Quantization
Ziqi Zhang, Chandan Mondal, Siqi Xu +2
The twist-3 transverse spin--dependent nucleon structure function arises in high-energy processes involving a transversely polarized nucleon. Its connection to quark--gluon c…

Dynamical gluon effects in twist-3 generalized parton distributions of the proton
Ziqi Zhang, Chandan Mondal, Siqi Xu +2
Within the Basis Light-Front Quantization framework, we systematically investigate the subleading-twist (twist-3) generalized parton distributions (GPDs) of the proton's valence qu…

Twist-3 Generalized Parton Distribution for the Proton from Basis Light-Front Quantization
Ziqi Zhang, Zhi Hu, Siqi Xu +3
We investigate the twist-3 generalized parton distributions (GPDs) for the valence quarks of the proton within the basis light-front quantization (BLFQ) framework. We first solve f…
