ABJM Dibaryon Spectroscopy

TL;DR

This paper explores the correspondence between wrapped D-branes and baryon-like operators in the AdS_4 imes CP^3/ABJM duality, focusing on D4-branes as dibaryon operators and their relation to giant gravitons.

Contribution

It extends the D-brane/operator map to the ABJM model, identifying D4-branes wrapping CP^2 as dibaryon operators and relating them to giant gravitons.

Findings

D4-branes wrapping CP^2 correspond to dibaryon operators.

These D-branes are half of the maximal giant gravitons on CP^3.

The work generalizes the brane/operator correspondence to the ABJM setting.

Abstract

We extend the proposal for a detailed map between wrapped D-branes in Anti-de Sitter space and baryon-like operators in the associated dual conformal field theory provided in hep-th/0202150 to the recently formulated AdS_4 \times CP^3/ABJM correspondence. In this example, the role of the dibaryon operator of the 3-dimensional CFT is played by a D4-brane wrapping a CP^2 \subset CP^3. This topologically stable D-brane in the AdS_4 \times CP^3 is nothing but one-half of the maximal giant graviton on CP^3.
