Description
How bad is the sign problem in QCD? It turns out that in the perturbative regime, the sign problem enters at $O(\alpha_s^3)$ in the strong coupling $\alpha_s$ to leading order. In this talk, I explain why the sign problem only enters at such high order, and I present the full $O(\alpha_s^3)$ result for it for all $\mu$ and $T$. I also explain how this result can be combined with future lattice simulations of “Phase quenched QCD” to determine the thermodynamics of deconfined matter to high accuracy.
