Taylor expansion and the Cauchy Residue Theorem for finite-density QCD

Abstract

We present an update on our efforts to determine the Taylor coefficients of the $\mu /T$ expansion of the pressure for finite-density QCD. Here, we explore alternatives based on the Cauchy Residue Theorem, which allows us to use a discretized contour to determine the desired spectral moments occurring in the Taylor expansion of QCD at zero chemical potential.
