Abstract

Purely leptonic decays of the charged D meson have been studied using the reaction e(+)e(-) --> DD-+(-) at a center of mass energy of 4.03 GeV. A search was performed for D --> mu v(mu), recoiling against a D- 0 or D+ which had been reconstructed from its hadronic decay products. A single event candidate was found in the reaction e(+)e(-) --> DD-(-), where D(+) --> pi(+)D(0) with the D-0 --> K- pi(+), and the reco iling D- decaying via D- --> mu(-)(v) over bar(mu). This yields a bran ching fraction value (D --> mu v mu) = 0.08(- 0.05 - 0.02)(+ 0.16 + 0. 05)% and a corresponding value of the pseudoscalar decay constant f(D) = 300(- 150 - 40)(+ 180 + 80) MeV.
