Abstract

We investigate the Taylor expansion of the baryon number susceptibility, and hence, pressure, in a series in the baryon chemical potential (μB) 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 μB=0. We find the radius of convergence of the series at various temperatures, and bound the location of the QCD critical point to be TE/Tc≈0.94 and μBE/T<1.8. We also investigate the extrapolation of various susceptibilities and linkages to finite chemical potential.
