Some Comments on N=1 Gauge Theories from Wrapped Branes

TL;DR

This paper investigates gauge theories realized on wrapped branes in Type IIB string theory, focusing on N=1 and N=2 supersymmetric Yang-Mills obtained via a topological twist on a supersymmetric cycle. It employs seven-dimensional SO(4) gauged supergravity to map bulk fields to space-time operators and to analyze the Maldacena-Nuñez N=1 background and related N=2 configurations. A central result is the identification of the gaugino condensate with a specific non-Abelian bulk gauge-field component, and the observation that the MN deformation corresponds to the IR dynamics of the boundary theory, with UV behavior matching expectations from AdS/CFT-like reasoning. The work also lays out a framework for generalized N=2→N=1 breaking by solving the associated BPS equations, highlighting challenges in constructing fully non-singular, multi-field solutions.

Abstract

We discuss various aspects of gauge theories realized on the world-volume of wrapped branes. In particular we analyze the coupling of SYM operators to space-time fields both in N=1 and N=2 models and give a description of the gluino condensate in the Maldacena-Nunez N=1 solution. We also explore the seven dimensional BPS equations relevant for these solutions and their generalizations.
