Abstract

We study the deconfinement transition line in QCD for quark chemical potentials up to μq5T\mu_q \sim 5 T (μB15T\mu_B \sim 15 T). To circumvent the sign problem we use the complex Langevin equation with gauge cooling. The plaquette gauge action is used with two flavors of naive Wilson fermions at a relatively heavy pion mass of roughly 1.3 GeV. A quadratic dependence describes the transition line well on the whole chemical potential range.
