| Abstract: | The infrared behavior of the running coupling constant in QCD has been studied using the Schwinger-Dyson equation of the gluon propagator based on the Slavnov-Taylor identities in axial gauge. It is shown that the infrared running coupling constant behavior g-2(Q2)=g2(μ2/Q2) in the infrared limit Q2/μ2→0. |
