Abstract
2-color QCD, i. e. QCD with the gauge group SU(2), is the simplest nonAbelian gauge theory without sign problem at finite quark density. Therefore its study
on the lattice is a benchmark for other non-perturbative approaches at finite density. To
provide such benchmarks we determine the minimal-Landau-gauge 2-point and 3-gluon
correlation functions of the gauge sector and the running gauge coupling at finite density. We observe no significant effects, except for some low-momentum screening of the
gluons at and above the supposed high-density phase transition.
