Abstract
One-prong decays into final states involving kaons are studied with about 161 000 events collected by the ALEPH detector from 1991 to 1995. Charged kaons are identified by dE/dx measurement, while 's are detected through their interaction in calorimeters. Branching ratios are measured for the inclusive mode, , where X can be any system of neutral particles, and for the exclusive modes where the first error is statistical and the second is systematical. Upper limits for and are also obtained. Mass spectra in the final states are investigated in order to study the relevant dynamics.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
