The quenched SU(2) fundamental scalar propagator in minimal Landau gauge

Understand

It is a long-standing question whether the confinement of matter fields in QCD has an imprint in the (gauge-dependent) correlation functions, especially the propagators.

• As the analytic structure plays an important role in this question, high-precision data is necessary for lattice investigations.
• Also, it is interesting how this depends on the dimensionality of the theory.
• To make a study over a wide range of parameters possible this suggests to use scalar particles.
