CHARGED KAON PRODUCTION IN TAU-DECAYS AT LEP
Kaon production in one prong tau decays has been studied using data collected with the DELPHI detector at the LEP collider Charged kaons were identified over a large momentum range by the DELPHI barrel Ring Imaging Cherenkov detector. The following branching ratios have been determined: BR(τ → Kντ)...

| description | Kaon production in one prong tau decays has been studied using data collected with the DELPHI detector at the LEP collider Charged kaons were identified over a large momentum range by the DELPHI barrel Ring Imaging Cherenkov detector. The following branching ratios have been determined: BR(τ → Kντ) = (0.85 ± 0.18) %, BR(τ → Kντ ≥ 0 neutrals) = (1.54 ± 0.24)%, BR(τ → Kντ ≥ 1 neutrals) = (0.69 ± 0.25)%. The result for the exclusive branching ratio is consistent with the Standard Model prediction based on τ - μ - e universality. In addition, tau decay into K*- was studied in the channel K*- → K-π0. The result BR(τ → K*-ντ) x BR(K*- → K-w0) = (0.57 ± 0.23)% was obtained. |
