    (4th week, Nov. 2-6) Dense QCD Matter and Compact Stars

    Over the last decade or so, blazing-fast progress has been made in perturbative computations of dense QCD matter. With the sign problem preventing the use of lattice methods, pQCD is a rare first-principles methods for gaining insight into the properties of quark matter and, consequently, constraining the properties of the neutron star equation of state.

    I will outline the current progress...

    (4th week, Nov. 2-6) Dense QCD Matter and Compact Stars

    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...

    (4th week, Nov. 2-6) Dense QCD Matter and Compact Stars

    We present recent results from lattice simulations of dense 2-colour QCD with Wilson fermions, with particular emphasis on (1) thermodynamics, including the speed of sound; (2) the structure of ground state fields at high density; and (3) simulations with an improved fermion action.
