Abstract: We study lattice QCD at nonvanishing chemical potential using the complex Langevin equation. We compare the results with multiparameter reweighting both from μ=0 and phase-quenched ensembles. We find a good agreement for lattice spacings below ≈0.15 fm. On coarser lattices the complex Langevin approach breaks down. Four flavors of staggered fermions are used on Nt=4, 6 and 8 lattices. For one ensemble we also use two flavors to investigate the effects of rooting.
