QCD Phase Diagram at small Baryon Densities from Imaginary mu: Status Report
Abstract
We summarize our recent results for the (T,mu)-phase diagram of Nf=3 QCD. Finding a strong variation of the critical endpoint muc with the quark mass m, we point out that an endpoint within reach of experiment requires fine-tuned quark masses. We further discuss the strategy and first data towards extending our results to the physical Nf=2+1 theory.
