Instanton Screening in the Nonperturbative Gluodynamics
Abstract
Description
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 these effects by Airy function asymptotics.
