Description
Using the QCD corrected spectral functions in finite Q2 sum rules, we compute the current coupling of the five low-lying mesons π, rho, K, Ksup(*), A1. For values of quark masses msub(u) = msub(d) = 250 MeV, msub(s) = 400 MeV and of the QCD scale parameter Λ = 500 MeV, we obtain striking agreement with experiment. (orig.)
