Abstract

We studied the QCD phase transition as a function of quark mass in the N_f=3 QCD at vanishing baryon density. Lattice simulations have been performed using Highly Improved Staggered Quarks on N_τ=6 lattices with quark masses that correspond to pion masses in the region 80 \lesssim m_π \lesssim 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 m^c_π\lesssim 45 MeV.
