We overview the current status and future perspectives of the QCD-based method of light-
cone sum rules. The two main versions of these sum rules, using light-meson and B-meson …

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 …

A bstract We revisit QCD calculations of radiative heavy meson decay form factors by
including the subleading power corrections from the twist-two photon distribution amplitude …

We study radiative decays of D s J*(2317) and D s J (2460) using light-cone QCD sum rules.
In particular, we consider the decay modes D s J*(2317)→ D s* γ and D s J (2460)→ D s (*) …

The rare decays Λ b→ Λ γ and Λ b→ Λ l+ l−(l= e, μ) are examined. We use QCD sum rules to
calculate the hadronic matrix elements governing the decays. The Λ polarization in the …

We use a light-cone sum rule (LCSR) analysis of the branching ratios of radiative meson
decays to constrain the value of the magnetic susceptibility of the quark condensate χ (μ) …

A bstract We propose a novel method to study flavor-changing neutral currents in the e+

Radiative magnetic dipole decays of heavy–light vector mesons into pseudoscalar mesons
V→ Pγ are considered within the relativistic quark model. The light quark is treated …
