A low-dimensional analogue of holographic baryons

Understand

Baryons in holographic QCD correspond to topological solitons in the bulk.

• The most prominent example is the Sakai-Sugimoto model, where the bulk soliton in the five-dimensional spacetime of AdS-type can be approximated by the flat space self-dual Yang-Mills instanton with a small size.
• Recently, the validity of this approximation has been verified by comparison with the numerical field theory solution.
• However, multi-solitons and solitons with finite density are currently beyond numerical field theory computations.
