Phase Quenched Lattice QCD at Finite Density and Temperature

Understand

We simulate 3-flavour lattice QCD at finite quark-number chemical potential mu in the phase-quenched approximation, close to the finite temperature transition.

• Working close to the critical quark mass, we find no evidence for the expected critical endpoint at small mu.
• We are performing further simulations aimed at calculating the equation-of-state of this theory outside of the superfluid domain, where its phase structure is expected to mimic the full theory.
