Abstract
Using the ARGUS detector at the storage ring DORIS II we have measured τ decays into three charged mesons containingK* mesons. Exploiting the good particle identification capabilities of the detector we have determined the following branching ratios:$$Br\left( {\tau ^ - \to \overline {K^{*0} } \pi ^ - v_\tau } \right) = \left( {0.25 \pm 0.10 \pm 0.05} \right)\% $$,Br→K*0Kvτ)= (0.20±0.05±0.04)%, andBr→K*−X0vτ) =(1.15±0.15−0.18+0.13)%.
