Holographic dense QCD in the Veneziano limit

TL;DR

This paper reviews recent advances in holographic QCD models, especially V-QCD, to understand dense QCD matter, phase diagrams, and neutron star properties where traditional methods are ineffective.

Contribution

It provides a comprehensive review of the V-QCD holographic model and its applications to dense QCD matter, neutron stars, and neutron star mergers.

Findings

Predicted phase diagram of dense QCD matter.

Modeled equation of state for neutron star matter.

Analyzed baryon properties and quark matter production.

Abstract

Solving the properties of dense QCD matter is an extremely challenging problem because standard theoretical tools do not work at intermediate densities. The gauge/gravity duality may help to provide answers in this region. I give a brief review of recent progress in this field, focusing on the V-QCD model, which is one of the most sophisticated holographic models of QCD. I discuss predictions for the phase diagram, the equation of state, and properties of baryons. I apply these results to analyze the properties of neutron stars and to quark matter production in neutron star mergers.
