The critical end point of quantum chromodynamics
  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\   T^E/T_c approximately 0.95 and mu_B^E/T^E approximately 1.1, where T_c is   the cross over temperature at zero chemical potential, and T^E   and mu_B^E are the temperature and the baryon chemical potential   at the critical end point. The small value of mu_B^E places it   in the range of observability in energy scans at the RHIC.
