Abstract We present results for the phase diagram of three flavor QCD for μB≲500 MeV. Our simulations are performed with imaginary chemical potential μI for which the fermion determinant is positive. Physical observables are then fitted by truncated Taylor series and continued to real chemical potential. We map out the location of the critical line Tc(μB) with an accuracy up to terms of order (μB/T)6. We also give first results on a determination of the critical endpoint of the transition and its quark mass dependence. Our results for the endpoint differ significantly from those obtained by other methods, and we discuss possible reasons for this.

QCD at finite temperature and chemical potential from Dyson–Schwinger equations (2018, methodology): “That this behaviour of the critical surface is by no means trivial and actually might not be realised has been argued by de Forcrand and Phillipsen from the results of lattice simulations with three degenerate quark flavours [29, 114, 141, 142].”
The chiral critical line of Nf = 2+1 QCD at zero and non-zero baryon density (2006, methodology): “Again, we note a shift of up to 10% in the coefficients compared to the R algorithm results [9].”
