Abstract

We present the first measurement of tau-decays to hadronic final states with a ϕ\phi-meson. This is based on 401.4 fb1^{-1} of data accumulated at the Belle experiment. The branching ratio obtained is B(τ±ϕK±ν)=(4.06±0.25±0.26)×105B(\tau^{\pm}\to\phi K^{\pm}\nu) = (4.06\pm 0.25\pm 0.26)\times 10^{-5}.
