Abstract

Using the ARGUS detector at the e⁺e^- storage ring DORIS II at DESY, we have studied semileptonic charmed meson decays through f{cyrillic}- and K^*0-electron correlations in continuum production. Evidence for the decay D^-_s→f{cyrillic}e^-v has been observed, with a branching ratio relative to the channel D^-_s→f{cyrillic}π^- determined to be 0.57±0.15±0.15. The decay D^-→K^*0e^-v was also seen, with a value of 0.55±0.08±0.10 extracted for the branching ratio relative to the channel D^-→K⁺π^-π^-. The ratio of the two measurements, after application of SU(3) corrections, implies a branching ratio for D^-_s→f{cyrillic}π^- of (2.4±1.0)%.
