| On Solving Schwinger-Dyson Equations for Non-Abelian Gauge Theory | ||
| Protvino, 1996.- p.7, refs.:7. | ||
A method of solving Schwinger-Dyson equations for the Green function generating functional of non-Abelian gauge theory is proposed. The method is based on an approximation of Schwinger-Dyson equations by exactly soluble equations. For the $SU(2)$ model the first step equations of the iteration scheme are solved which define a gauge field propagator. Except the usual perturbative solution, a non-perturbative solution is found which corresponds to the spontaneous symmetry breaking and obeys non-singular ("constant") behaviour of the propagator in the infrared region
