The Nonperturbative Equation for the Infrared \Pi_{44}(0) - Limit in the Temporal Axial Gauge

Abstract

The nonperturbative equation for the infrared $\Pi_{44}(0)$-limit is built by using the Slavnov-Taylor identity to define the three-gluon vertex function in the temporal axial gauge. We found that all vertex corrections should be taken into account along with the standard ring graphs to keep the gauge covariance throughout calculations and to give correctly the nonperturbative $g^3$-term. This term is explicitly calculated and compared with the previously known results.
