Resum

One-prong τ decays into final states involving kaons are studied with about 161 000 τ+τ-events collected by the ALEPH detector from 1991 to 1995. Charged kaons are identified by dE/dx measurement, while K0L's are detected through their interaction in calorimeters. Branching ratios are measured for the inclusive mode, B(τ-→ K-Xντ) = (1.52±0.04±0.04)%, where X can be any system of neutral particles, and for the exclusive modes B(τ-→ K-ντ) = (6.96 ± 0.25 ± 0.14) × 10-3, B(τ-→ K-π0ντ) = (4.44 ± 0.26 ± 0.24) × 10-3, B(τ-→ K-π0π0ντ) = (0.56 ± 0.20 ± 0.15) × 10-3, B(τ-→ K-π0π0π0ντ) = (0.37 ± 0.21 ± 0.11) × 10-3, B(τ-→ K-K0ντ) = (1.62 ± 0.21 ± 0.11) × 10-3, B(τ-→ K-K0π0ντ) = (1.43 ± 0.25 ± 0.15) × 10-3, B(τ-→ K0π-ντ) = (9.28 ± 0.45 ±0.34) × 10-3. B(τ-→ K0π-π0ντ) = (3.47 ± 0.53 ± 0.37) × 10-3. where the first error is statistical and the second is systematical. Upper limits for B(τ-→ K0π-π0π0ντ) and B(τ-→ K-K0π0π0ντ) are also obtained. Mass spectra in the final states are investigated in order to study the relevant dynamics.
