Quark and gluon entanglement in the proton based on a light-front Hamiltonian
Chen Qian, Siqi Xu, Yang-Guang Yang +1
Given that the wave function of a proton can be derived relativistically and nonperturbatively from a light-front quantized Hamiltonian, investigating the quantum correlation betwe…
Double parton distributions of the proton from basis light-front quantization
Tian-Cai Peng, Zhi Hu, Sreeraj Nair +5
Within the basis light-front quantization framework, we systematically investigate the unpolarized and longitudinally polarized double parton distributions (DPDs) of quarks inside…
Towards a first principles light-front Hamiltonian for the nucleon
Siqi Xu, Yiping Liu, Chandan Mondal +4
We solve the nucleon's wave functions from the eigenstates of the light-front quantum chromodynamics Hamiltonian for the first time, using a fully relativistic and nonperturbative…
Chiral-odd gluon generalized parton distributions in the proton: A light-front quantization approach
Bolang Lin, Sreeraj Nair, Chandan Mondal +5
Within the basis light-front quantization (BLFQ) framework, we evaluate the gluon chiral-odd generalized parton distributions (GPDs) inside the proton at zero skewness. We employ t…
Gravitational form factor of charmonium from shear stress
Tianyang Hu, Xianghui Cao, Siqi Xu +3
Based on our recent analysis of the hadronic matrix element of the stress-energy tensor in covariant light front dynamics, we extract the charmonium gravitational form factor $D(Q^…
Energy momentum tensor on and off the light cone: exposition with scalar Yukawa theory
Xianghui Cao, Siqi Xu, Yang Li +4
We compute the gravitational form factors , and of the scalar Yukawa theory using both the light-cone and covariant perturbation theory at the one-loop level.…
Transverse structure of the proton beyond leading twist: A light-front Hamiltonian approach
Zhimin Zhu, Siqi Xu, Jiatong Wu +7
Within the Basis Light-Front Quantization framework, we systematically investigate the subleading twist (twist-3) transverse-momentum-dependent parton distribution functions (TMDs)…
Flavor asymmetry from the non-perturbative nucleon sea
Yihan Duan, Siqi Xu, Shan Cheng +3
We demonstrate, in the context of a scalar version of the chiral effective field theory, that the multi-sea quark contribution to the nucleon is significant and highly non-trivial…
Stress out of charmonia
Siqi Xu, Xianghui Cao, Tianyang Hu +3
We investigate the gravitational form factors of charmonium. Our method is based on a Hamiltonian formalism on the light front known as basis light-front quantization. The charmoni…
Gravitational Form Factors and Mechanical Properties of Quarks in Protons: A Basis Light-Front Quantization Approach
Sreeraj Nair, Chandan Mondal, Siqi Xu +3
We compute the gravitational form factors (GFFs) and study their applications for the description of the mechanical properties such as the pressure, shear force distributions, and…
Transverse-momentum-dependent gluon distributions of proton within basis light-front quantization
Hongyao Yu, Zhi Hu, Siqi Xu +3
Gluon transverse-momentum dependent distributions (TMDs) are very important for revealing the internal structure of the proton. They correspond to a variety of experiments and are…

Yiping Liu, Siqi Xu, Chandan Mondal +2
We obtain all the leading-twist quark generalized parton distributions (GPDs) inside the proton at nonzero skewness within the basis light-front quantization framework. We employ t…
