  The total and differential cross sections of elastic proton-proton and
proton-antiproton scattering are studied in a holographic QCD model,
considering the Pomeron and Reggeon exchanges in the Regge regime. In our model
setup, the Pomeron and Reggeon exchanges are described by the Reggeized spin-2
glueball and vector meson propagators, respectively. How those contributions
change with the energy is explicitly shown, focusing on the contribution
ratios. The adjustable parameters included in the model are determined with the
experimental data, and it is presented that the resulting total and
differential cross sections are consistent with the data in a wide kinematic
region.
