Leptonic decays of the $D_{s}$ meson
The purely leptonic decays Ds -> mu nu and Ds -> tau nu are studied in a sample of four million hadronic Z decays collected in 1991--1995 with the ALEPH detector at LEP. The tau nu channel is analyzed in the tau -> e nu nubar and mu nu nubar final states. The branching fraction measurements...
