摘要
We study two colors lattice QCD (QC2D) with two flavors of staggered fermions on 404 and 324 lattices with lattice spacing a = 0.048 fm in the wide range of the quark chemical potential ??q. Our focus is on the confinement-deconfinement transition in this theory. Thus we compute the string tension from the Wilson loops and the static quark free energy from the Polyakov loops. We find that the deconfinement transition found earlier in the range ??q 800???1000 MeV is shifted to higher values. This shift is attributed to decreasing of the lattice spacing used in our simulations in comparison with the earlier study.
