Abstract
We review the results of 0710.4292 [hep-th] where we study the embedding of spacetime filling D7-branes in β-deformed backgrounds. This corresponds to flavoring β-deformed N = 4 super Yang-Mills. For the supersymmetric and the more general non-supersymmetric three parameter deformations, we study quadratic fluctuations of a probe D7-brane wrapped on a deformed three-sphere, which correspond to mesonic configurations of the dual field theory. We manage to solve their equations exactly in the presence of a non-trivial coupling between scalar and vector modes induced by the deformation. We find a mesonic mass spectrum which is discrete, with a mass gap and a Zeeman-like splitting occurs. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
