Deep inelastic scattering from holographic spin-one hadrons

We study deep inelastic scattering structure functions from hadrons using different holographic dual models which describe the strongly coupled regime of gauge theories in the large N limit. Particularly, we consider scalar and vector mesons obtained from holographic descriptions with fundamental degrees of freedom, corresponding to N = 2 supersymmetric and non-supersymmetric Yang-Mills theories. We explicitly obtain analytic expressions for the full set of eight structure functions, i.e., F-1, F-2, g(1), g(2), b(1), b(2), b(3), b(4), arising from the standard decomposition of the hadronic tensor of spin-one hadrons. We obtain the relations 2F(1) = F-2 and 2b(1) = b(2). In addition, we find b(1) similar to O(F-1) as suggested by Hoodbhoy, Jaffe and Manohar for vector mesons. Also, we find new relations among some of these structure functions.
