Ratio F[subscript K]/F[subscript pi] in QCD
We determine the ratio F[subscript K]/F[subscript pi] in QCD with N[subscript f]=2+1 flavors of sea quarks, based on a series of lattice calculations with three different lattice spacings, large volumes, and a simulated pion mass reaching down to about 190 MeV. We obtain F[subscript K]/F[subscript...
