Penrose limit of T dual of Maldacena-Nastase solution and dual orbifold field theory

Abstract

Here we study the Penrose limit of the T dual of the Maldacena-Nastase 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-typeoperators is found as a symmetry of the (2+1)-dimensional confining theory with spontaneous supersymmetry breaking.
