摘要：

I report on the current status of QCD phase diagram at vanishing baryon density. I focus on the QCD phase diagram with three degenerate quark flavor using Highly Improved Staggered Quarks on N-tau = 6 lattices. No evidence of a first order phase transition in the pion mass window of 80 less than or similar to m(pi) less than or similar to 230 MeV is found. The pion mass at the critical point where the chiral first order phase transition ends is estimated to be m(pi)(c) less than or similar to 45 MeV.
