Abstract

After presenting a brief review of how simulations of QCD with imaginary chemical potential can be used to extract physical results, we analyse the phase structure of QCD with four flavours of dynamical fermions in the finite temperature - imaginary chemical potential plane, and discuss perspectives for realistic calculations.
