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 (μ). Non-zero μ-s are reached by means of multiparameter reweighting. The dynamical staggered simulations were carried out for n_f = 2 + 1 flavors with physical quark masses on 4 × 12³ lattices.
