HADRONIC CORRELATORS AND CONDENSATE FLUCTUATIONS IN QCD VACUUM

Phenomenological results of equal time, point to point spatial correla tion functions of hadronic currents are used to deduce the structure o f the QCD vacuum, It is found that a model with only quark condensate is not adequate to explain the observations. Inclusion of condensate f luctuations (explicit four point structure in the vacuum) leads to exc ellent overall agreement with the phenomenological curves and paramete rs in various channels.
