Abstract: (Springer)

Using the ARGUS detector at the DORIS II storage ring, we have studied τ decays with one or three charged particles in the final state, obtaining the following values for the branching ratios: BR(τ−→e−

\bar v_e v_\tau

)=(17.3±0.4±0.5)% BR(τ−→μ−\bar v_\muv_\tau)=(17.2±0.4±0.5)%,BR(τ−→π−vπ)+BR(τ−→K−vπ)=(11.7±0.6±0.8)% and BR(π−→3-prong)=(13.3±0.3±0.8)%. These measurements confirm the present world averages with a precision, in each case, comparable to the error on the combination of all previous results.
