摘要
We present recent measurements of tau decays into final states with kaons, which are based on several hundred million tau(+)tau(-) pairs produced in electron-positron annihilation data collected with the BABAR detector. These measurements can be used to determine the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-us vertical bar with a tiny systematic error and in two different methods affected by different systematic effects.
