Signals of confinement in green functions of SU(2) yang-mills theory

The removal of center vortices from SU(2) Yang-Mills theory lattice configurations was discussed. The gluon form factor, running coupling constant and ghost form factor were also discussed in the Landau gauge for the full and the vortex removed theory. A strong suppression of the running coupling constant and the gluon form factor at low momenta were observed in the latter case. It was also found that the IR singularity of the ghost form factor disappears in the latter case.
