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 …

I review recent progress on understanding QCD dynamics involved in exclusive B meson
decays. Different frameworks, including light-cone sum rules, QCD factorization, perturbative …

In this paper, we test the self-consistencies of the standard and the covariant light-front quark
model and study the zero-mode issue via the decay constants of pseudoscalar (P), vector …

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 present the analysis of exclusive 0−→ 0− semileptonic heavy meson decays using the
constituent quark model based on the light-front quantization. Our model is constrained by …

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 …

The frame and scale dependence of the pair-term contribution to the electromagnetic form
factor of a spin-zero composite system of two-fermions is studied within the Light Front. The …

We investigate the transition form factors f+(q 2) and f-(q 2)[or f 0 (q 2)] for the exclusive
semileptonic B→ D ℓ ν ℓ (ℓ= e, μ, τ) decays in the standard light-front quark model based on …

A bstract In this paper, we calculate the matrix element and form factors of vector-to-vector
(VI→ V II) transition within the standard light-front (SLF) and covariant light-front (CLF) quark …
