Open Strings on Plane waves and their Yang-Mills duals

TL;DR

This paper explores the correspondence between open strings in a specific plane wave background derived from a string theory setup and their dual gauge theory operators, extending the AdS/CFT correspondence to include open strings.

Contribution

It introduces a detailed analysis of open strings in a plane wave limit of $AdS_5\times S^5/Z_2$ and identifies their dual gauge invariant operators in the $Sp(N)$ gauge theory.

Abstract

We study the plane wave limit of $AdS_5\times S^5/Z_2$ which arises as the near horizon geometry of D3-branes at an orientifold 7-plane in type I' theory. We analyze string theory in the resulting plane wave background which contains open strings. We identify gauge invariant operators in the dual $Sp(N)$ gauge theory with unoriented closed and open string states.
