Abstract. Since the turn of the millennium there has been
tremendous progress in understanding QCD at finite chemical potential, m. Apart from qualitative results obtained using
models, and exact results at very large m obtained in weak coupling theory, there has
been tremendous progress in getting exact and quantitative results from lattice
simulations. I summarize the status of lattice QCD at finite chemical potential
-- locating the critical end-point in the QCD phase diagram, predicting
event-to-event fluctuation rates of conserved quantities, and finding the rate
of strangeness production.
Keywords. Quantum chromodynamics; Fermion-sign problem;
critical end-point.
