We investigate the magnetic dipole decays V→ P γ of various heavy-flavored mesons such
as (D, D*, D s, D s*, η c, J/ψ) and (B, B*, B s, B s*, η b, Υ) using the light-front quark model …

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

Under two different scenarios for the light scalar mesons, we investigate the transition form
factors of B (B s) mesons decay into a scalar meson in the perturbative QCD approach. In …

A bstract We calculate the next-to-leading order QCD corrections to B to scalar meson form
factors from QCD light-cone sum rules with B meson light-cone distribution amplitudes. We …

We investigate the structure of ground-state heavy mesons within the light-front quark model,
utilizing wave functions derived from the single Gaussian ansatz (SGA) and the Gaussian …

The mass spectra and wave functions of both 1 S and 2 S state heavy pseudoscalar (P) and
vector (V) mesons are analyzed within the light-front quark model. Important empirical …

We investigate the interplay among the pion's form factor, transverse momentum dependent
distributions (TMDs), and parton distribution functions (PDFs) extending our light-front quark …

In the light-front quark model (LFQM) amenable to the simultaneous study of both the mass
spectroscopy and the wave function related observables, we examine the decay constants …

The shape of the hadronic form factor f+(q 2) in the decay D 0→ K-e+ ν e has been
measured in a model independent analysis and compared with theoretical calculations. We …

We report on determinations of| V ub| resulting from studies of the branching fraction and q 2
distributions in exclusive semileptonic B decays that proceed via the b→ u transition. Our …
