Abstract

Based on a series of lattice calculations we determine the ratio F K/Fπ in QCD. With experimental data from kaon decay and nuclear double beta decay, we obtain a precise determination of |V us|. Our simulation includes 2 + 1 flavours of sea quarks, with three lattice spacings, large volumes and a simulated pion mass reaching down to about 190MeV for a full control over the systematic uncertainties.
