is the simplest non-abelian gauge theory with fermions without sign proble
m. Therefore its study on the lattice is a benchmark for other non-perturb
ative approaches at finite density.\n\nWe study the Landau-gauge 2-point a
nd 3-point correlation functions of the gauge sector and the running gauge
coupling at finite density\, and compare them to the vacuum case.\n\nWe o
bserved no significant effect of the finite density\, except for some scre
ening of the gluons. Moreover\, no strong signature of the phase change (
if not a lattice artifact) in the properties of quarks are observed in the
gauge sector\, in contrast to the finite-temperature case. This indicates
that the finite-density physics is essentially driven by the quarks\, rat
her than by the gluons.\n\nhttps://makondo.ugr.es/event/0/session/91/contr
