Thermodynamics of Deconfined QCD at Small and Large Chemical Potential

Abstract

We present large $N_f$ QCD/QED as a test bed for improved pressure calculations, show how to apply the hints obtained on optimized renormalization scales at large $N_f$ to finite $N_f=2$, and compare the results to recent lattice data.
