Exclusive photoproduction in photon-proton diffractive scattering: A light-front Hamiltonian approach
Xiaoyi Wu, Zhi Hu, Chandan Mondal +5
We investigate the cross-section for exclusive production in photon-proton diffractive scattering within the Basis Light-Front Quantization (BLFQ) framework. The leading-ord…
Spin-orbit correlation of quarks within quarkonium
Tianyang Hu, Xianghui Cao, Siqi Xu +3
The spin-orbit correlation (SOC) provides a unique probe into the internal spin structure of hadrons. Defined via the parity-odd (P-odd) energy-momentum tensor (EMT), this observab…
Generalized parton distributions of valence, sea, and gluon components of the proton
Yiping Liu, Siqi Xu, Chandan Mondal +2
We compute the generalized parton distributions (GPDs) of valence quarks, sea quarks, and gluons in the proton using light-front wave functions obtained within the basis light-fron…
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…
Spin entanglement signatures of proton from a light-front Hamiltonian
Chen Qian, Siqi Xu, Yang-Guang Yang +1
Quantum entanglement provides a quantitative probe of the internal structure of hadrons and offers a sensitive means to study the quantum correlation in the hadron wave functions.…
Non-perturbative flavor asymmetry in the nucleon and deuteron: The light-front Hamiltonian effective field theory approach
Xianghui Cao, Shan Cheng, Yihan Duan +3
We investigate non-perturbative multi-pion contributions to nucleon flavor asymmetry within the framework of Light-Front Hamiltonian Effective Field Theory (LFHEFT). Utilizing a Fo…
