Abstract

The light front wavefunction obtained from anti-de Sitter Quantum Chromodynamics is used to calculate the light cone distribution amplitudes for ρ and K^* vector mesons. These distribution amplitudes are then utilized to calculate the B → ρ, K^* transition form factors via light cone sum rules. Two-parameter fits of our results for low to intermediate momentum transfer q² that includes the QCD lattice data at high q² are presented. Consequently, we give predictions for the semileptoic B → ρℓ ν and dileptonic B → K^* μ⁺ μ^- decays.
