We present measurements of the flavor-changing neutral current decays B→ K ℓ+ ℓ-and B→
K* ℓ+ ℓ-, where ℓ+ ℓ-is either an e+ e-or μ+ μ-pair. The data sample comprises 229× 10 6 Υ …

In the covariant light-front quark model, we investigate the form factors of B c decays into D,
D*, D s, D s*, η c, J/ψ, B, B*, B s, and B s* mesons. The form factors in the spacelike region …

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 …

The light-cone method provides a convenient nonperturbative tool to study the heavy-to-light
form factors. We construct a light-cone quark model utilizing the soft collinear effective …

We present evidence for the flavor-changing neutral current decay B→ K* ℓ+ ℓ-and a

In the covariant light-front quark model, we investigate the B c→ hc, χ c 0, 1, 2 form factors.
The form factors are evaluated in the spacelike kinematic region and are recasted to the …
