Leptonic decays of the $D_{s}$ meson and production of orbitally excited D and $D_{s}$ mesons
The purely leptonic decays D/sub s/ to mu nu and D/sub s/ to tau nu are studied in a sample of four million hadronic Z decays collected in 1991-1995 with the ALEPH detector at LEP. A linear discriminant analysis is used to measure the branching fraction B(D/sub s/ to mu nu )=(0.64+or-0.08[stat]+or-0...
