Supersymmetry and flavor in a sugra dual of N=1 Yang-Mills

Abstract

Some field theory aspects can be addressed holographically by introducing D-branes in the string theory duals. In this work, we study this issue in the framework of a dual of N=1 YM, the so-called Maldacena-Nunez model. Some supersymmetric embeddings for D5-brane probes are found and they are interpreted as the addition of fundamental flavors to the gauge theory. This allows to give a dual description of some known aspects of N=1 SQCD and to compute a mass spectrum of mesons.
