Leptonic decays of the $D_{s}$ meson

Mostrar otras versiones (2)

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...

description 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 are used to extract the pseudoscalar decay constant f_Ds.
