Description
The total and differential cross sections of elastic nucleon-nucleon scattering processes are studied in the framework of holographic QCD, considering the Pomeron and Reggeon exchange in the Regge regime. In our model setup, the Pomeron and Reggeon exchange are described by the Reggeized spin-2 glueball and vector meson propagator, respectively. How those contributions change with the energy is discussed in detail, focusing on the contribution ratios. The adjustable parameters involved 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.
