title = "Towards the QCD phase diagram from analytical continuation",
abstract = "We calculate the QCD cross-over temperature, the equation of state and fluctuations of conserved charges at finite density by analytical continuation from imaginary to real chemical potentials. Our calculations are based on new continuum extrapolated lattice simulations using the 4stout staggered actions with a lattice resolution up to Nt=16. The simulation parameters are tuned such that the strangeness neutrality is maintained, as it is in heavy ion collisions.",

note = "Funding Information: Very recently, a similar study (but using μB = 0 ensembles) have been published, where the κ was extracted from fluctuation data [25]. Interestingly the data seem to prefer a negative freeze-out curvature, which is also true in our Fig. 2 and also in [18]. The full systematics of the comparison between lattice and experiment is yet to be understood. Acknowledgements: This project was supported by the Deutsche Forschungsgemeinschaft grant SFB/TR55. C.
