摘要：We investigate the critical end point (CEP) of QCD with two flavours of light dynamical quarks
at finite lattice cutoff a = 1/4T using a Taylor expansion of the baryon number susceptibility. We
find a strong volume dependence of the position of the critical end point. In the large volume
limit we obtain TE/Tc 0.95 and mE
B /TE 1.1, where Tc is the cross over temperature at zero
chemical potential, and TE and mE
B are the temperature and the baryon chemical potential at the
critical end point. The small value of mE
B places it in the range of observability in energy scans at
the RHIC.
