Abstract: (Elsevier)
In this paper we construct trial functions for the field configurations and study the interaction of pseudoparticles. Then we perform numerical simulations of the effective theory, integrating over collective coordinates. The main qualitative features of the phenomenological instanton liquid model are confirmed. We have evaluated their density in vacuum, as well as the instantonic contribution to the gluon condensate, to the static potential between quarks and to some correlation functions.- GAUGE FIELD THEORY: SU(2)
