Baryons And Branes In Anti de Sitter Space

TL;DR

This paper explores how various baryonic and brane configurations in Anti-de Sitter space correspond to features of four-dimensional gauge theories, providing insights into the gauge/string duality.

Contribution

It details the mapping of gauge theory features to brane configurations in AdS space, including baryon vertices, gluon bound states, and domain walls.

Findings

Baryon vertices couple N external charges in SU(N).

Bound states of k gluons are represented in the brane framework.

Strings in different representations correspond to specific brane configurations.

Abstract

In the mapping from four-dimensional gauge theories to string theory in $AdS$ space, many features of gauge theory can be described by branes wrapped in different ways on $\S^5$, $\RP^5$, or subspaces thereof. These include a baryon vertex coupling N external charges in the fundamental representation of SU(N), a bound state of $k$ gluons in SO(2k) gauge theory, strings coupled to external charges in the spinor representation of the gauge group, and domain walls across which the low energy gauge group changes.
