Penrose limit of T-dual of MNa solution and dual orbifold field theory

TL;DR

This paper investigates how T-duality affects the Penrose limit of the MNa solution and its dual field theory, revealing oscillator mode matching and symmetry effects on confining operators.

Contribution

It provides the first detailed analysis of the T-dual of the MNa solution's Penrose limit and its impact on the dual field theory's operator structure.

Findings

String oscillator modes match field theory modes after T-duality.

T-duality rearranges long 'annulon-type' operators in the confining theory.

T-duality acts as a symmetry in the 2+1 dimensional confining theory with spontaneous SUSY breaking.

Abstract

In this paper we study the Penrose limit of the T-dual of the MNa solution and its field theory dual, in order to better understand the effect of T-duality in this case. We find a matching of string pp wave oscillators and their masses to the field theory modes, that are rearranged after T-duality. The effect of T-duality on the long "annulon-type" operators is found, as a symmetry of the 2+1 dimensional confining theory with spontaneous susy breaking.
