Query: Lattice simulations of the QCD chiral transition at real baryon density   State-of-the-art lattice QCD studies of hot and dense strongly interacting
matter currently rely on extrapolation from zero or imaginary chemical
potentials. The ill-posedness of numerical analytic continuation puts severe
limitations on the reliability of such methods. Here we use the more direct
sign reweighting method to perform lattice QCD simulation of the QCD chiral
transition at finite real baryon density on phenomenologically relevant
lattices. This method does not require analytic continuation and avoids the
overlap problem associated with generic reweighting schemes, so has only
statistical but no uncontrolled systematic uncertainties for a fixed lattice
setup. This opens up a new window to study hot and dense strongly interacting
matter from first principles. We perform simulations up to a baryochemical
potential-temperature ratio of $\mu_B/T=2.5$ covering most of the RHIC Beam
Energy Scan range in the chemical potential. We also clarify the connection of
the approach to the more traditional phase reweighting method.
