John Gracey (University of Liverpool) – Infrared QCD propagators and effective gluon mass
Room 101 2-5 Kirkby Place, PlymouthSince the start of the century the behaviour of the gluon and ghost propagators have been widely studied on the lattice at low momenta. In the Landau gauge the gluon propagator freezes to a non-zero finite value indicating the presence of a mass scale. Such a scale could be explained from a field theory point
