Giant Graviton Correlators from Dual SU(N) super Yang-Mills Theory

TL;DR

This paper computes exact correlation functions in N=4 super Yang-Mills theory, identifies operators related to half-BPS states, and explores implications for giant gravitons in the AdS/CFT correspondence.

Contribution

It provides a systematic construction of operators corresponding to half-BPS states and analyzes their role in dual giant graviton configurations.

Findings

Exact correlation functions for certain operators are obtained.

A correspondence between operators and half-BPS representations is established.

Boundary contributions in U(N) gauge theory are systematically identified.

Abstract

Certain correlation functions are computed exactly in the zero coupling limit of N=4 super Yang-Mills theory with gauge group SU(N). A set of linearly independent operators that are in one-to-one correspondence with the half-BPS representations of the SU(N) gauge theory is given. These results are used to study giant gravitons in the dual AdS5xS5 string theory. In addition, for the U(N) gauge theory, we explain how to systematically identify contributions coming from the boundary degrees of freedom.
