Elliptic Models, Type IIB Orientifolds and the Ads/CFT Correspondence

TL;DR

This paper explores the supergravity descriptions of specific type IIB string theory models with elliptic structures, orientifolds, and branes, and matches their chiral primary states to gauge theory operators via AdS/CFT correspondence.

Contribution

It provides a detailed analysis of the supergravity duals of elliptic type IIB models with orientifolds and branes, and establishes the correspondence between supergravity states and gauge theory operators.

Findings

Identification of chiral primary states in supergravity

Matching of supergravity states to gauge-invariant operators

Analysis of gauge theories with up to two factors

Abstract

We analyze the large N supergravity descriptions of the class of type IIB models T-dual to elliptic type IIA brane configurations containing two orientifold 6-planes and up to two NS 5-branes. The T-dual IIB configurations contain N D3-branes in the background of an orientifold 7-plane and, in some models, a Z_2 orbifold and/or D7-branes, which give rise to four-dimensional N=2 (or N=4) gauge theories with at most two factors. We identify the chiral primary states of the supergravity theories, and match them to gauge invariant operators of the corresponding superconformal theories using Maldacena's duality.
