abstract
We study the mass spectrum and decay constants of light and heavy mesons in a soft-wall holographic approach, using the correspondence of string theory in Anti-de Sitter space and conformal field theory in physical space-time.

Light cone QCD sum rules produce the form factors T1V(q²=0), T2V(q²=0), T1A(q²=0), T2A(q²=0) for Ξ*bb → Ξb γ, from which the decay width is calculated.
