### Abstract

Based on universal arguments it is believed that there is a critical point (E) in QCD on the temperature (T) versus chemical potential (μ) 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 μ 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 μ_{E} = 725±35 MeV. For the critical temperature at μ = 0 we obtained T_{c} = 172 ± 3 MeV.
