First Lattice Study of Ghost Propagators in SU(2) and SU(3) Gauge Theories
Abstract
We present a numerical study of the ghost propagators in Landau gauge for SU(2) and SU(3) gauge theories at β=2.7 and β=6.0, respectively. Analyzing different lattice sizes up to 324, we find small finite size effects. Down to the smallest available momenta, we observe no evidence for dipole behaviour of the ghost propagators.
