  The cross sections of the high energy proton-proton scattering are studied in
a holographic QCD model, focusing on the Regge regime. In our model setup, the
involved nonperturbative partonic dynamics is described by the Pomeron
exchange, which is realized by applying the Reggeized spin-2 particle
propagator together with the proton gravitational form factor obtained from the
bottom-up AdS/QCD model. Our model includes three adjustable parameters which
are to be fitted by experimental data. We show that both the resulting
differential and total cross sections are consistent with data, including the
ones recently measured at $\sqrt{s}=13$ TeV by the TOTEM collaboration at the
LHC. Our results imply that the present framework works well in the considered
TeV scale, and further applications to other high energy scattering processes,
in which the involved strong interaction can be approximated by the Pomeron
exchange, are possible.
