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-

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 ...

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.

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.

Vacuum loops in light-front field theory
Physics Letters B, 2020 We demonstrate that vacuum diagrams in the genuine light front (LF) field theory are non-zero, in spite of simple kinematical counter-arguments (positivity and conservation of the LF momentum p+, absence of Fourier zero mode).

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.
