In this work we calculate the form factors of the A, and hb semileptonic decay using the QCD sum rules approach. We found that the form factors sum rules are more stable than the respective mass sum rules, and we get a decay rate for A, compatible with experiment.
Mixing of multi-quark components in the non-singlet scalar mesons and the flavor singlet L(1405) baryon with negative parity are studied in the QCD sum rule. We propose a formulation to evaluate cross-correlators of qq(qqq) and qqqq ðqqqqqÞ operators and to define mixing of different Fock states in
