LEPTONIC DECAYS OF THE D_s MESON AT LEP

摘要

Results on BR(D_s → Tν) from the LEP experiments are presented here. With a recent measurement the ALEPH collaboration has also explored the channel D_s → μν showing the first evidence at LEP for such a signal. The D_s decay constant is extracted from the measurements of the two branching ratios showing consistency between all the results.
