Four quark flavors are used in the analysis. Though the method is quite expensive small lattices show an indication for a triple-point connecting three different phases on the phase diagram.5 pages, 6 figures, talk given at 'Extreme QCD', August 2-5 2005, Swansea, Wales, UKHigh Energy Physics - Latticetext
