Abstract
From a sample of about 160k candidates collected with the ALEPH detector at LEP between 1991 and 1995, lepton decays involving are studied. The associated production in decays is also investigated. The branching ratios are measured for the inclusive decay , where can be anything, and for the exclusive decays The decay is studied for the first time, giving a branching ratio The channels , , , , and are also investigated. In addition, mass spectra in the and final states are analysed to provide information on the intermediate states produced in the decays.
