The QCD transition line from lattice simulations

Abstract

Abstract We present our new results for the QCD transition line at finite chemical potential μB from first principle, lattice QCD simulations. We extrapolate our results from imaginary chemical potentials, up to μ B ≈ 300 ​ MeV . We obtain the most precise value for the transition temperature, the curvature of the QCD phase diagram and its fourth order correction. The results are continuum extrapolated, based on Nt = 10, 12, 16 lattices. We also study the height and width of the peak of the chiral susceptibility and how they change with increasing chemical potential. We find that both of them are consistent with a constant, which does not indicate any criticality in our explored
