Deconfinement transition line with the Complex Langevin equation up to $μ/T \sim 5$

We study the deconfinement transition line in QCD for quark chemical potentials up to $μ_q \sim 5 T$ ($μ_B \sim 15 T$). 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.
