After a brief review of the experimental findings of d∗(2380) and several theoretical efforts to
interpret its structure, the study of d∗(2380) on the quark–gluon degrees of freedom is …

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 …

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 present a unified Dyson-Schwinger equation treatment of static and electromagnetic
properties of pseudoscalar and vector mesons, and scalar and axial-vector diquark …

The electromagnetic form factors of vector mesons are calculated in an explicitly Poincaré
covariant formulation, based on the Dyson-Schwinger equations of QCD, that respects …

The issue of resulting in the same physical observables with different current components, in
particular from the minus current, has been challenging in the light-front quark model …

In this work, the electromagnetic and gravitational form factors of a spin-3/2 particle, Δ
resonance, are simultaneously calculated with the help of a relativistic covariant quark …

Generalized parton distribution functions (GPDs) of spin-3/2 particles are defined for the first
time in this paper. Eight unpolarized and eight polarized GPDs are found. In the forward limit …

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 …
