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.

• Properties of hot and dense matter from relativistic heavy ion collisions (2015, methodology): “Therefore, the above Taylor expansion for the pressure is employed in order to determine the QCD equation of state for small chemical potentials [64,67,241].”
• Higher order fluctuations and correlations of conserved charges from lattice QCD (2018, background): “Finally, higher order fluctuations of conserved charges are proportional to powers of the correlation length and are expected to diverge at the critical point, thus providing an important signature for its experimental detection [9, 24, 25].”
