Electron g-2 in Light-front Quantization [PDF]
Physics Letters B, 2014 Basis Light-front Quantization has been proposed as a nonperturbative framework for solving quantum field theory. We apply this approach to Quantum Electrodynamics and explicitly solve for the light-front wave function of a physical electron.

Basis light-front quantization approach to photon
Physics Letters B, 2022 We solve for the light-front wave functions (LFWFs) of the physical photon from the eigenvectors of the light-front quantum electrodynamics (QED) Hamiltonian with the aim to determine its bare photon and electron-positron Fock components.

Transverse structure of the pion beyond leading twist with basis light-front quantization [PDF]
Physics Letters B, 2023 We investigate the twist-3 transverse-momentum-dependent parton distribution functions (TMDs) of the pion with basis light-front quantization. The twist-3 TMDs are not independent and can be decomposed into twist-2 and genuine twist-3 terms from the ...

Light-front quantization with the light cone gauge [PDF]
Canadian Journal of Physics, 2016 The Dirac procedure for dealing with constraints is applied to the quantization of gauge theories on the light front. The light cone gauge is used in conjunction with the first-class constraints that arise and the resulting Dirac brackets are found. These gauge conditions are not used to eliminate degrees of freedom from the action prior to applying ...

Diffractive charmonium spectrum in high energy collisions in the basis light-front quantization approach [PDF]
Physics Letters B, 2017 Using the charmonium light-front wavefunctions obtained by diagonalizing an effective Hamiltonian with the one-gluon exchange interaction and a confining potential inspired by light-front holography in the basis light-front quantization formalism, we ...

LIGHT-FRONT QUANTIZATION OF GAUGE THEORIES [PDF]
Strong Coupling Gauge Theories and Effective Field Theories, 2003 Light-front wavefunctions provide a frame-independent representation of hadrons in terms of their physical quark and gluon degrees of freedom. The light-front Hamiltonian formalism provides new nonperturbative methods for obtaining the QCD spectrum and eigensolutions, including resolvant methods, variational techniques, and discretized light-front ...

Recent progress in basis light-front quantization [PDF]
Hadron Spectroscopy and Structure, 2020 Basis Light-front Quantization (BLFQ) is a nonperturbative approach to quantum field theory. In this paper, we report our recent progress in applying BLFQ to the positronium system in QED and to the meson and the baryon system in QCD. We present preliminary results on the mass spectrum, light-front wave functions and other observables of these systems,

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.
