We evaluate fπ/mρ, fK/mρ, 1/fρ, and mφ/(fφmρ), extrapolated to physical quark mass, zero lattice spacing and infinite volume, for lattice QCD with Wilson quarks in the valence (quenched) approximation. The predicted ratios differ from experiment by amounts ranging from 12% to 17% equivalent to between 0.9 and 2.8 times the corresponding statistical(More)
We evaluate pseudoscalar, vector, spin 1/2 and spin 3/2 baryon masses predicted by lattice QCD with Wilson quarks in the valence (quenched) approximation for a range of different values of lattice spacing, lattice volume and quark mass. Extrapolating these results to physical quark mass, then to zero lattice spacing and infinite volume we obtain values for(More)
We evaluate fπ/mρ, fK/mρ, 1/fρ, and mφ/(fφmρ), extrapolated to physical quark mass, zero lattice spacing and infinite volume, for lattice QCD with Wilson quarks in the valence (quenched) approximation. The predicted mφ/(fφmρ) differs from experiment by less than its statistical uncertainty of approximately 15%. The other three constants are 10% to 20% below(More)
We obtain estimates of several hadron mass ratios, for Wilson quarks in the valence (quenched) approximation, extrapolated to physical quark mass, infinite volume and zero lattice spacing. permanent address Dept. of Mathematics, Trinity College, Dublin 2, Ireland talk presented by D.
