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.

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 ...

Heavy-light mesons on the light front
European Physical Journal C: Particles and Fields, 2020 We study the heavy-light mesons within basis light-front quantization. The resulting mass spectra of D, $$D_s$$ Ds , B, and $$B_s$$ Bs agree reasonably well with experiments. We also predict states which could be measured in the near future. In the light-

Electron form factors in Basis Light-front Quantization [PDF]
In this paper, we evaluate the electromagnetic and gravitational form factors as well as the corresponding generalized parton distributions of the electron using the Basis Light-front Quantization approach to QED. We compare our results with those from light-front perturbation theory. We adopt a novel basis with its scale depending on the constituents'

Statistical physics and light-front quantization [PDF]
Physical Review D, 2004 Light-front quantization has important advantages for describing relativistic statistical systems, particularly systems for which boost invariance is essential, such as the fireball created in a heavy ion collisions. In this paper we develop light-front field theory at finite temperature and density with special attention to quantum chromodynamics.

Quantization in a general light-front frame [PDF]
Physical Review D, 2004 In this paper, we study the question of quantization of quantum field theories in a general light-front frame. We quantize scalar, fermion as well as gauge field theories in a systematic manner carrying out the Hamiltonian analysis carefully. The decomposition of the fields into positive and negative frequency terms needs to be done carefully after ...

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.
