Description

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 nf=2+1 dynamical staggered quarks with semi-realistic masses on Lt=4 lattices. Our results is TE=160±3.5 MeV and μE=725±35 MeV. For the critical temperature at μ=0 we obtained Tc=172±3 MeV. (orig.)
