abstract
We study two related problems in the context of a supergravity dual to N=1 SYM. One of the problems is finding kappa symmetric D5-brane probes in this particular background. The other is the use of these probes to add flavors to the gauge theory. We find a rich and mathematically appealing structure of the supersymmetric embeddings of a D5-brane probe in this background. Besides, we compute the mass spectrum of the low energy excitations of N=1 SQCD (mesons) and match our results with some field theory aspects known from the study of supersymmetric gauge theories with a small number of flavors.

Twisted-Circle Compactifications of SQCD-like Theories and Holography
New regular type IIB supergravity backgrounds are constructed for twisted-circle compactifications of SQCD-like theories, and their regularity forces the anomaly-free condition N_f = 2N_c.
