QCD at finite chemical potential with six time slices

We investigate the Taylor expansion of the baryon number susceptibility, and hence, pressure, in a series in the baryon chemical potential (mu(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(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-E/T-c approximate to 0: 94 and mu(E)(B)/T < 1.8. We also investigate the extrapolation of various susceptibilities and linkages to finite chemical potential.
