摘要：

Based on universal arguments it is believed that there is a critical point (E) in QCD on the temperature (T) versus chemical potential (mu) plane, which is of extreme importance for heavy-ion experiments. Using finite size scaling and a recently proposed lattice method to study QCD at finite mu we determine the location of E in QCD with n(f) = 2 + 1 dynamical staggered quarks with semi-realistic masses on L-t = 4 lattices. Our result is T-E = 160 +/- 3.5 MeV and mu(E) = 725 +/- 35 MeV. For the critical temperature at mu = 0 we obtained T-c = 172 +/- 3 MeV.
