Abstract: (Springer)
We reanalyse the Weinberg type sum rules in the light of the Laplace transform sum rule and including the leading non-perturbative effects. We then estimate the light quark invariant masses; the pion decay amplitudefπ and theA1 coupling and mass. Using other type of sum rules, we derive bounds on the pseudoscalar decay amplitudesfp(P≡π, K, D, F) as well as on the gluon component of theU(1)A meson mass. Our main results are summarized in Sect. 4.- CURRENT ALGEBRA: SUM RULE
