Deep inelastic scattering of leptons from hadrons at small values the Bjorken parameter x is studied superstring theory. In particular, we focus on single-flavored scalar and vector mesons in large N limit. This terms different holographic dual models with flavor Dp-branes type IIA IIB theories, strong coupling limit corresponding gauge theories. We derive hadronic tensor structure functions for polarized mesons. obtain eight parameter. The main result that new relations Callan-Gross several functions. These have similarities all Dp-brane consider. would suggest their universal character, therefore, it possible they hold strongly coupled QCD
