Abstract
We calculate deep inelastic structure functions for mesons in the D3-D7 brane model, that incorporates flavour to the AdS/CFT correspondence. We consider two different prescriptions for the hadronic current dual: a gauge field in the AdS bulk and a gauge field on the D7 brane. We also calculate elastic form factors in both cases. We compare our results with other holographic models.
Comments: V2: We included a new section with several plots comparing the structure functions of the models considered. We moved some calculation details to an appendix. Typos corrected. One reference included. 18 pages. 3 figures containing 9 plots
