Abstract

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^- {Mathematical expression})=(17.3±0.4±0.5)% BR(τ^-→μ^- {Mathematical expression})=(17.2±0.4±0.5)%,BR(τ^-→π^-v_π)+BR(τ^-→K^-v_π)=(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.
