A note on the string dual of N=1 SQCD-like theories

In this note vie describe how N = 1 SQCD-like theories with a large number of flavors can be given a dual description in terms of a string background containing a large number of additional D5-branes. The dual geometries account for the backreaction of the additional branes: they depend on the ratio between the number of flavors and colors of the gauge theory. This note is based on [1]. We present here also a new set of solutions, which are not included in the original paper. (C) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
