Comment on chiral symmetry restoration at finite density in large-$N_c$ QCD

TL;DR

This paper defends the use of Skyrmions in hyperspherical unit cells for modeling dense nuclear matter, countering previous criticisms based on invalid assumptions.

Contribution

It clarifies the validity of Skyrmion-based models in describing chiral symmetry restoration at finite density in large-$N_c$ QCD.

Findings

Criticism of Skyrmion models is based on invalid assumptions.

Skyrmion approach remains a valid method for dense nuclear matter.

Supports the continued use of hyperspherical unit cells in this context.

Abstract

In the article "On chiral symmetry restoration at finite density in large-$N_c$ QCD" by Adhikari, Cohen, Ayyagari and Strother [Phys. Rev. C 83, 065201 (2011)] the description of dense nuclear matter by means of Skyrmions in hyperspherical unit cells is severely criticized. We point out that this criticism is based on invalid assumptions and therefore unwarranted.
