Reweighting enables exploration of finite μ.

Results consistent with theoretical expectations.

Abstract

We present numerical results on the static quark--anti-quark grand canonical potential in full QCD at non-vanishing temperature ($T$) and quark chemical potential ($\mu$). Non-zero $\mu$-s are reached by means of multi-parameter reweighting. The dynamical staggered simulations were carried out for $n_f=2+1$ flavors with physical quark masses on $4\times 12^3$ lattices.
