Abstract
We evaluate f(pi)/m(rho), f(K)/m(rho), 1/f(rho), and m(phi)/(f(phi)m(r ho)), extrapolated to physical quark mass, zero lattice spacing and in finite volume, for lattice QCD with Wilson quarks in the valence (quen ched) approximation. The predicted ratios differ from experiment by am ounts ranging from 12% to 17% equivalent to between 0.9 and 2.8 times the corresponding statistical uncertainties.
