✦ Synopsis
We present results on the QCD phase diagram for small densities without reweighting.
Our simulations are
performed with an imaginary chemical potential ,LLI for which the fermion determinant is positive. On an 83 x 4 lattice with 2 flavors of staggered quarks, we map out the pseudo-critical temperature Tc(pl). For pr/T 2 7r/3, this is an analytic function whose Taylor expansion converges rapidly, with truncation errors smaller than statistical ones. The result is analytically continued to give the location of the pseudo-critical line for real ps 5 500 MeV.
