Study of two color QCD on large lattices

Understand

We study two colors lattice QCD (QC$_2$D) with two flavors of staggered fermions on $40^4$ and $32^4$ lattices with lattice spacing $a =0.048$~fm in the wide range of the quark chemical potential $\mu_q$.

• 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 $\mu_q \approx 800 - 1000$ MeV is shifted to higher values.
