摘要：We report results of the investigation of physics at finite chemical potential using the method
of Taylor expansion of the free energy for staggered quarks with mp ≃ 210 MeV on Nt = 6
lattices. When the spatial volume is (4/TE)3 we estimate that the location of the critical end
point is at TE/Tc ≃ 0.94(1) and mE
B /TE ≃ 1.8(1). This is to be compared to an earlier estimate
of TE/Tc ≃ 0.95(1) and mE
B /TE ≃ 1.3(3) made on similar spatial volumes and quark masses but
with Nt = 4.
