Towards the Hadron-Quark Continuity Via a Topology Change in Compact Stars

Understand

We construct a generalized EFT approach to dense compact-star matter that exploits the CCP for hadron-quark continuity at high density, hidden topology and hidden symmetries of QCD.

• No Landau-Ginzburg-Wilsonian-type phase transition is involved.
• The microscopic DoF of QCD possibly intervening at high baryonic density are traded in for fractionalized topological objects.
• Essential in the description are symmetries invisible in QCD in the matter-free vacuum: Scale symmetry, flavor local symmetry and parity-doubling.
