摘要：We studied the QCD phase transition as a function of quark mass in the Nf = 3 QCD at vanishing baryon density. Lattice simulations have been performed using Highly Improved Staggered Quarks on Nt = 6 lattices with quark masses that correspond to pion masses in the region 80 . mp . 230 MeV. We found no evidence of the first order phase transition in the current pion mass window. The pion mass at the critical point where the first order phase transition starts is estimated to be mcp . 45 MeV.
