Instanton bags, high density holographic QCD, and chiral symmetry restoration
Instanton bags, high density holographic QCD, and chiral symmetry restoration
We describe the simplest example of an instanton bag in Euclidean space. It consists of a monopole wall and a Kaluza-Klein monopole wall, lifted to one higher dimension, trapping the instanton charge in the middle. This object has finite instanton density in a three-dimensional volume. Baryon physics in holographic QCD …
