The questions of how the bulk of the Universe's visible mass emerges and how it is manifest
in the existence and properties of hadrons are profound, and probe the heart of strongly …

We study the decay constants and form factors of the ground-state s-wave and low-lying p-
wave mesons within a covariant light-front approach. Numerical results of the form factors for …

A manifestly covariant formalism is used as a guide to construct a covariant extension of the
light-front quark model. Our analysis demonstrates in detail that covariance necessarily …

We calculate the decay constants of light and heavy-light pseudoscalar and vector mesons
with improved soft-wall holographic wavefuntions, which take into account the effects of both …

We investigate the exclusive semileptonic B c→(D, η c, B, B s) ℓ ν ℓ, η b→ B c ℓ ν ℓ (ℓ= e, μ,
τ) decays using the light-front quark model constrained by the variational principle for the …

We study the form factors of vector mesons using a covariant fermion field theory model in
3+ 1 dimensions. Performing a light-front (LF) calculation in the q+= 0 frame in parallel with a …

We analyze the matrix element of the electroweak current between qq vector meson states
in the framework of a covariant extension of the light-front formalism. The light-front matrix …

We investigate the elastic form factors of the ρ meson in the light-front quark model (LFQM).
With the phenomenologically accessible meson vertices including the one obtained by the …

With the recent advances in the Hamiltonian renormalization program, light-front dynamics
LFD appears to be a promising technique to impose the relativistic treatment of hadrons. In …

We find that the zero mode (q+= 0 mode of a continuum theory) contribution is crucial to
obtaining the correct values of the light-front current J− in the Drell-Yan (q+= 0) frame. In the …
