Abstract

A numerical analysis of the correlators is made for various models of the QCD vacuum. A good description of data is demonstrated for quite different models with 〈G²〉=(1.5±0.5) 〈G²〉_SVZ, the precise value being model dependent . It is not possible to extract further details of vacuum structure, such as 〈G⁴〉 from available data.
