We will study open and hidden charm scalar meson resonances within two different models. The first one is a direct application of a chiral Lagrangian already used to study flavor …
We present the first complete results for the semileptonic and rare radiative form factors of the B meson's weak decay into a light vector meson (ρ, ω, K*, φ) in the light-cone sum rule …

We evaluate the mass shift of isospin-averaged D-meson in the nuclear medium. Borel- transformed QCD sum rules are used to describe an interaction between the D-meson and a …
We present a study of the heavy-light spectrum and of the D-and B-meson decay constants. The results were obtained in the quenched approximation, by using the nonperturbatively …

I review recent progress on understanding QCD dynamics involved in exclusive B meson decays. Different frameworks, including light-cone sum rules, QCD factorization, perturbative …
We study the semileptonic transitions B c→ η c, J/ψ, D, D*, B, B*, B s, B s* in the framework of a relativistic constituent quark model. We use experimental data on leptonic J/ψ decay …
We present the first lattice QCD calculation with realistic sea quark content of the D+-meson decay constant f D+. We use the MILC Collaboration's publicly available ensembles of lattice …
A lattice QCD calculation of the B→ Dl ν decay form factors is presented. We obtain the value of the form factor h+(w) at the zero-recoil limit w= 1 with high precision by considering …

A new method for the model-independent determination of the light-cone distribution amplitude of the B-meson in heavy quark effective theory (HQET) is proposed by combining …
