From an analysis of the ionisation energy loss of charged particles selected from 110326 e+e- candidates recorded by the OPAL detector at e+e- centre-of-mass energies near the Z0 resonance, we determine the one-prong tau decay branching ratios:
where the notation refers to a , an , a , or a , and where the first uncertainty is statistical and the second is systematic.
