Abstract

We report a measurement of the branching ratio B(D⁺ → ρ⁰ℓ⁺ν_ℓ)/B(D⁺ → K̄*⁰ℓ⁺ν_ℓ) from the Fermilab charm hadroproduction experiment E791. Based on signals of 49 ± 17 events in the D⁺ → ρ⁰e⁺ν_e mode and 54 ± 18 events in the D⁺ → ρ⁰μ⁺ν_μ mode, we measure B(D⁺ → ρ⁰e⁺ν_e)/B(D⁺ → K̄*⁰e⁺ν_e) = 0.045 ± 0.014 ± 0.009, B(D⁺ → ρ⁰μ⁺ν_μ)/B(D⁺ → K̄*⁰μ⁺ν_μ) = 0.051 ± 0.015 ± 0.009. Combining the results from both the electronic and muonic modes, we obtain B(D⁺ → ρ⁰ℓ⁺ν_ℓ)/B(D⁺ → K̄*⁰ℓ⁺ν_ℓ) = 0.047 ± 0.013. This result is compared to theoretical predictions.
