Abstract
In this work we study unpolarized spin $1/2$ baryonic deep inelastic scattering (DIS) in the regime of large Bjorken parameter $x$. We calculate the corresponding structure functions ${F}_{1,2}(x,{q}^{2})$. Our approach is based on an AdS/QCD model with a deformed background, where we consider an exponential factor in the ${\mathrm{AdS}}_{5}$ metric. Such a deformation implies the introduction of an anomalous dimension in the model. Our results for the structure functions are consistent with those found in the literature from experimental data.
