Color defects in a gauge condensate

Abstract

The model of an approximate non-perturbative calculations in the SU(3) gauge theory is offered. This approach is based on the separation of initial degrees of freedom on ordered and disordered phases. The ordered phase is almost classical degrees of freedom, the disordered phase is completely quantum degrees of freedom. Using some approximations and simplifications for 2 and 4-points Green's functions an effective Lagrangian describing both phases from the SU(3) Lagrangian is obtained. The calculations show that ordered phase is squeezed by disordered phase into defects. These defects are: an infinite flux tube filled with longitudinal color electric and magnetic fields; a color electric hedgehog; a defect having either two color electric dipoles + two color magnetic dipoles or two color electric dipoles or two color magnetic dipoles. It assumed that the color defects are quantum excitations in a gauge condensate. The equations for the disordered phase are an analog of Ginzburg - Landau equation.
