Abstract

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\(\hat m_s /\hat m_d ,\hat m_u \hat m_d \); the pion decay amplitudefπ and theA1 coupling and mass. Using other type of sum rules, we derive bounds on the pseudoscalar decay amplitudesf p (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.
