QCD at finite chemical potential with six time slices
2008
We investigate the Taylor expansion of the baryon number susceptibility, and hence, pressure, in a series in the baryon chemical potential ({mu}{sub B}) through a lattice simulation with two flavors of light dynamical staggered quarks at a finer lattice cutoff a=1/6T. We determine the QCD cross over coupling at {mu}{sub B}=0. We find the radius of convergence of the series at various temperatures, and bound the location of the QCD critical point to be T{sup E}/T{sub c}{approx_equal}0.94 and {mu}{sub B}{sup E}/T<1.8. We also investigate the extrapolation of various susceptibilities and linkages to finite chemical potential.
