Contribution

It provides new pp-wave limit analyses of models with orientifolds and D7-branes, and proposes mappings between string states and gauge theory operators.

Findings

Identified pp-wave limits with open and closed strings

Derived maps between string states and gauge operators

Analyzed models with compact null directions

Abstract

We study the pp-wave limits of various elliptic models with orientifold planes and D7-branes, as well as the pp-wave limit of an orientifold of adS_5 x T^{11}. Many of the limits contain both open and closed strings. We also present pp-wave limits of theories which give rise to a compact null direction and contain open strings. Maps between the string theory states and gauge theory operators are proposed.
