Effects of Screening of the Instantons in Nonperturbative QCD

Abstract

The gluon fields screening in the stochastic vacuum of gluodynamics is studied. The effective action is derived for the instanton interacting with nonperturbative fields. Quantum nonperturbative effects are shown to affect greatly the shape of instanton. The power asymptotics x^{-2} of the classical "instanton's profile function" at large distances is replaced due to yhese effects by Airy function asymptotics x^{-1/4} exp(-const\cdot x^{3/2}).
