12 Feb 2021 S. Borsanyi Z. Fodor J. N. Guenther R. Kara S. D. Katz P. Parotto A. Pasztor C. Ratti K. K. Szabo

Taylor expansion of the equation of state of QCD suffers from shortcomings at chemical potentials $\mu_B \geq (2-2.5)T$. First, one faces difficulties inherent in performing such an expansion with a limited number of coefficients; second, higher order coefficients determined from lattice calculations suffer from a poor signal-to-noise ratio...
