| Abstract: | Approximate solutions for the gluon and ghost propagators as well as the running coupling in Landau gauge Yang–Mills theories are presented. These propagators obtained from the corresponding Dyson–Schwinger equations are in remarkable agreement with those of recent lattice calculations. The resulting running coupling possesses an infrared fixed point, αS(0) = 8:92=N for all gauge groups SU(N). Above one GeV the running coupling rapidly approaches its perturbative form. |
