The Elusiveness of Infrared Critical Exponents in Landau Gauge Yang--Mills Theories

C. S. Fischer, R. Alkofer, H. Reinhardt

We solve a truncated system of coupled Dyson-Schwinger equations for the gluon and ghost propagators in SU($N_c$) Yang-Mills theories in Faddeev-Popov quantization on a four-torus.…
