摘要：

Working in the improved ladder approximation to QCD, we calculate the two point correlation functions for the composite operators psi-M-psiBAR. From these we extract mass values and decay constants for the lowest lying scalar, vector and axial vector mesons. Considering the naivety of the approximation used, and that we have no free parameters once the QCD scale is set, the results are surprisingly good.
