摘要：

We study deep inelastic scattering for vector and axial vector mesons in the holographic D4-D8 brane model. We consider tree level contributions with one particle in the final hadronic state. We obtain the unpolarized structure functions F-1 and F-2 for the rho and a(1) mesons for q(2) < 80 GeV2 and 0.2 < x < 1. We find that the ratio F-2/(2xF(1)) is approximately equal to one for some ranges of x and q(2), satisfying the Callan-Gross relation.
