Deep inelastic scattering cross sections from the gauge/string duality

Dierential cross sections of deep inelastic scattering of charged leptons from hadrons are investigated by using the gauge/string duality. We consider vector mesons de- rived from dierent holographic dual models obtaining a general expression. We focus on the strongly coupled regime of dual gauge theories for dierent values of the Bjorken param- eter. We nd new predictions which are particularly interesting for dierential scattering cross sections of polarized leptons scattered o polarized vector mesons. We also carry out a detailed comparison of the moments of the structure functions with lattice QCD results.
