Abstract
Some QCD-inspired spectral function sum rules are discussed, in view of the most recent experimental results on scalar and pseudoscalar mesons. Estimates are performed of the weak-decay amplitudes of 0− radial excitations, of the current quark mass ratiom g/md and of the quark vacuum condensate ratio á[`(y)] s ys ñ/á[`(y)] u yu ñ\langle \bar \psi _s \psi _s \rangle /\langle \bar \psi _u \psi _u \rangle .Pubblicazioni consigliate
