Abstract

We report a measurement of the absolutely inclusive semileptonic branching fractions of D^- and D⁰ mesons, using a data sample of 22.3 pb^-1 collected with BES detector at BEPC e⁺ e^- Collider at √s = 4.03 GeV and based on the method of "combinative D⁺ and D⁰ single and double tags". The measured values of the branching fractions for D^-→e^- X and D⁰→e^- X are (21.8 ± 8.5 ± 4.2)% and (8.9 ± 3.0 ± 1,6)%, respectively. The measured ratio of the branching fractions is BF(D^-→e^- X)/BF(D⁰→e^- X) = 2.4 ± 1.7 ± 0.8.
