Abstract

From a sample of about 75000 τ decays identified with the ALEPH detector, K0 production in 1-prong hadronic decays is investigated by tagging the KL0 component in a hadronic calorimeter. Results are given for the final states ντh-K0 and ντh-π0K0 where the h- is separated into π and K contributions by means of the dE/dx measurement in the central detector. The resulting branching ratios are: (Bτ → ντπ-K0) = (0.88±0.14±0.09)%, (Bτ → ντK-K0) = (0.29±0 12±0.03)%, (Bτ → ντπ-π0K0) = (0.33±0.14±0.07)% and (Bτ → ντK-π0K0) = (0.05±0.05 ±0.01)%. The K* decay rate in the K0π channel agrees with that in the Kπ0 mode: the combined value for the branching ratio is (Bτ → ντK*-) = (1.45±0.13±0.11)%.
