Quarkyonic Effective Field Theory, Quark-Nucleon Duality and Ghosts

Understand

We present a field theoretical description of quarkyonic matter consisting of quark, nucleon and ghost fields coupling to mesonic degrees of freedom.

• The ghosts are present to cancel over-counting of nucleon states that are Pauli blocked by the quark Fermi sea.
• Such a theory becomes an effective field theory of nucleons at low baryon density, and as such will reproduce nucleonic matter phenomenology.
• This theory can accommodate chiral symmetry restoration and the dynamical generation of a shell of nucleons at the Fermi surface.
