Abstract

The beauty to up quark coupling constant |V_ub| can be extracted from B→ρe⁺ν_e combined with the form factors for D→K^*e⁺ν_e and B→Vℓ⁺ℓ^- and D→ρe⁺ν _e. Using the entire CLEO-c ψ(3770)→DD̄ event sample, corresponding to an integrated luminosity of 818 pb^-1 and approximately 5.4×106 DD̄ events, we measure the form factors for the decays D0→ρ^-e⁺ν_e and D ⁺→ρ0e⁺ν_e for the first time and the branching fractions with improved precision. A four-dimensional unbinned maximum likelihood fit determines the form factor ratios to be V(0)/A ₁(0)=1.48±0.15±0.05 and A₂(0)/A ₁(0)=0.83±0.11±0.04. Assuming Cabibbo-Kobayashi-Maskawa unitarity, the known D meson lifetimes, and our measured branching fractions we obtain the form factor normalizations A₁(0), A₂(0), and V(0). We also present a measurement of the branching fraction for D ⁺→ωe⁺ν_e with improved precision.
