1/N corrections to $F_1$ and $F_2$ structure functions of vector mesons from holography

Understand

The structure functions $F_1$ and $F_2$ of the hadronic tensor of vector mesons are obtained at order $1/N$ and strong coupling using the gauge/gravity duality.

• We find that the large $N$ limit and the high energy one do not commute.
• Thus, by considering the high energy limit first, our results of the first moments of $F_1$ for the rho meson agree well with those from lattice QCD, with an important improvement of the accuracy with respect to the holographic dual calculation in the planar limit.
