We present our analysis on the high energy scattering processes in the framework of the holographic QCD, assuming that the Pomeron exchange gives a dominant contribution to the cross sections. Focusing on the two-body scattering, we employ the Brower–Polchinski–Strassler–Tan Pomeron exchange kernel to describe the strong gluonic interaction, and utilize the bottom-up AdS/QCD models to obtain the density distributions of the involved hadrons in the five-dimensional AdS space, to calculate the total cross sections. Considering the unpolarized deep inelastic scattering at small Bjorken \(x\) and the high energy hadron-hadron scattering, we show that our calculations are consistent with the presently available experimental data. Our predictions made via this framework can be tested at various experimental facilities in the future.
