Abstract
The first measurement of tau's hadronic decay with a ϕ-meson is reported from Belle collaboration. A clear ϕ-meson peak is first detected, based on high statistic 401 fb −1 of data: B r ( τ − → ϕ K − ν ) = ( 4.05 ± 0.25 ± 0.26 ) × 10 −5 is obtained. Also, a possible ϕ K − resonance is examined, but no clear evidence is found.
