Generalized parton distributions of gluon in proton: A light-front quantization approach

Physics Letters B, 2023
We solve for the gluon generalized parton distributions (GPDs) inside the proton at zero skewness, focusing specifically on leading twist chiral-even GPDs.

Chiral sum rule on the light front and the 3D image of the pion

Physics Letters B, 2023
The lightest meson, the pion, features two faces – one is the elementary Goldstone boson of QCD and the other is the structured bound state of quarks and gluons.

Structure of light-front vacuum sector diagrams

Physics Letters B, 2019
We study the structure of scalar field light-front quantization vacuum graphs. In instant-time quantization both non-vacuum and vacuum graphs can equivalently be described by either the off-shell four-dimensional Feynman diagram approach or the on-shell ...

Transverse momentum structure of proton within the basis light-front quantization framework

Physics Letters B, 2022
We obtain the leading-twist valence quark transverse-momentum-dependent parton distribution functions (TMD PDFs) for the proton within the basis light-front quantization (BLFQ) framework.

Compactification near and on the light front [PDF]

, 1999
We address problems associated with compactification near and on the light front. In perturbative scalar field theory we illustrate and clarify the relationships among three approaches: (1) quantization on a space-like surface close to a light front; (2)

Nucleon structure from basis light-front quantization [PDF]

Physical Review D, 2021
We produce the light-front wave functions (LFWFs) of the nucleon from a basis light-front ap- proach in the leading Fock sector representation. We solve for the mass eigenstates from a light-front effective Hamiltonian, which includes a confining potential adopted from light-front holography in the transverse direction, a longitudinal confinement, and ...

Heavy quarkonium in a holographic basis

Physics Letters B, 2016
We study the heavy quarkonium within the basis light-front quantization approach. We implement the one-gluon exchange interaction and a confining potential inspired by light-front holography.

Applications of Light-Front QCD [PDF]

, 2004
Light-front Fock state wavefunctions encode the bound state properties of hadrons in terms of their quark and gluon degrees of freedom at the amplitude level.

Wilson loop in light-front quantization [PDF]

Physical Review D, 2017
Using Dirac's method for the quantization of constrained systems QED is canonically quantized in the front-form in a gauge which is the light-front analog of the Weyl gauge. From the obtained vacuum wave functional the spatial Wilson loop is calculated.
