Transverse structure of the pion beyond leading twist with basis light-front quantization
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 Field Theory on Current Quantum Computers
Entropy, 2021 We present a quantum algorithm for simulation of quantum field theory in the light-front formulation and demonstrate how existing quantum devices can be used to study the structure of bound states in relativistic nuclear physics.

Light mesons with one dynamical gluon on the light front
Physics Letters B, 2022 We obtain the light meson mass spectroscopy from the light-front quantum chromodynamics (QCD) Hamiltonian, determined for their constituent quark-antiquark and quark-antiquark-gluon Fock components, together with a three-dimensional confinement.

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 ...

Frame-Independence of Exclusive Amplitudes in the Light-Front Quantization [PDF]
Physical Review D, 2000 While the particle-number-conserving convolution formalism established in the Drell-Yan-West reference frame is frequently used to compute exclusive amplitudes in the light-front quantization, this formalism is limited to only those frames where the ...

Light-Front Quantization and AdS/QCD: An Overview
Journal of Physics: Conference Series, 2011 We give an overview of the light-front holographic approach to strongly coupled QCD, whereby a confining gauge theory, quantized on the light front, is mapped to a higher-dimensional anti de Sitter (AdS) space.

Thermal Field Theory and Generalized Light Front Coordinates [PDF]
Physical Review D, 2003 The dependence of thermal field theory on the surface of quantization and on the velocity of the heat bath is investigated by working in general coordinates that are arbitrary linear combinations of the Minkowski coordinates.

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,
