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

Abstract

We study the deconfinement transition line in QCD for quark chemical potentials up to ${\mu }_q\sim 5T$ (${\mu }_B\sim 15T$). 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.
