We demonstrate that the axial anomaly drives a new critical point at low temperature in the QCD phase diagram and leads to a smooth crossover between the hadronic and color superconducting phases.4 pages, 5 figures, to appear in the Proceedings of Quark Matter 2006 held in ShanghaiHigh Energy Physics - Phenomenologytext
