In this work, the high-energy hadron-hadron scattering is studied in the framework of holographic AdS/QCD models, using the Brower–Polchinski–Strassler–Tan Pomeron exchange kernel and gravitational form factors. We apply the configurational entropy techniques to estimate the slope of the total cross section for the total hadron-hadron cross sections at high-energies. A good agreement is derived between our approach and the total cross section for combinations that include the pion-nucleon, nucleon-nucleon, and pion-pion, as well as for any high-energy data with inclusion of data from the TOTEM collaboration at the LHC and approximated by the Pomeron exchange. In the case of pion-nucleon and pion-pion scattering, the agreement for the critical points to the differential configurational entropy can be reached within 1.1% even without the involvement of any extra parameters.
