abstract
We investigate the nature of the deconfinement and Roberge-Weiss transition in the heavy quark regime for finite real and imaginary chemical potential within the functional approach to continuum QCD. We extract the critical phase boundary between the first order and cross-over regions, and also explore tricritical scaling. Our results confirm previous ones from finite volume lattice studies.

QCD in the heavy dense regime for general $N_c$: On the existence of quarkyonic matter
An effective lattice calculation for heavy quarks at any Nc finds a first-order baryon onset and p~Nc scaling in the dense phase, consistent with quarkyonic matter, with continuum limits still out of reach.
