Description
Mapping the QCD phase structure at finite baryon density remains a challenging problem because direct simulations are hindered by the sign problem. By analyzing results at vanishing and purely imaginary chemical potentials, we identified strangeness susceptibility, in the case of strangeness neutrality, as a proxy for the chiral transition. We exploit this observation to investigate the QCD transition line at large baryon chemical potentials up to $550$ MeV, thanks to a Taylor expansion up to NNNNLO based on extreme-statistics runs on a $16^3 \times 8$ lattice. We also investigate the non-strangeness neutral scenario, and discuss possible implications for the existence of a critical point.
