Deconfined, Massive Quark Phase at High Density and Compact Stars: A Holographic Study

Understand

In Hoyos et al.

• (arXiv:1603.02943) a holographic D3/D7 system was used to describe a deconfined yet massive quark phase of QCD at finite density, concluding that the equation of state of such a phase was not stiff enough to support exotic dense stars.
• That analysis used a hard quark mass to represent the dynamical mass and assumed a conformal gauge background.
• Here we phenomenologically adjust the D3/D7 system to include a running anomalous dimension for the quark condensate.
