We analyze within the framework of resonance chiral theory the ? S A μ A ν ? and ? S V μ V ν ? three-point Green functions, where S , A μ and V μ are short for scalar, axial-vector and vector S U ( 3 ) hadronic currents. We construct the necessary Lagrangian such that the Green functions fulfill the asymptotic constraints, at large momenta, imposed by QCD at leading order. We study the implications of our results on the spectrum of scalars in the large ? N C limit, and analyze their decays.
