Abstract

In 60 pb^-1 of data taken on the ψ(3770) resonance with the CLEO-c detector, we find eight D⁺ → μ ⁺ ν decay candidates that are mostly signal, containing only one estimated background. Using this statistically compelling sample, we measure a value of B(D ⁺ → μ ⁺ ν) = (3.5 ± 1.4 ± 0.6) × 10^-4, and determine f_D+ = (202 ± 41 ± 17) MeV.
