Open AccessInfrared saturation and phases of gauge theories with BRST symmetry
We investigate the infrared limit of the quantum equation of motion of the gauge boson propagator in various gauges and models with a BRST symmetry. We find that the saturation of this equation at low momenta ...

Open AccessPhase structure and the gluon propagator of SU(2) gauge-Higgs model in two dimensions
We study numerically the phase structure and the gluon propagator of the SU(2) gauge-Higgs model in two dimensions. First, we calculate gauge-invariant quantities, in particular the static potential from Wilso...
