Total hadronic and photonic cross sections and the nuclear configurational entropy concept

Abstract

In the framework of eikonalized mini-jet model, contributions from gluon recombination effects are studied for the free proton in $pp$ and $\bar p p$ reactions. The nuclear configurational entropy is then used to calculate the main parameters to estimate the total proton cross sections for the recent data LHC, also corroborating to previous developments. Photoproduction cross sections with vector meson dominance and saturation effects for both total hadronic and photonic cross sections at a high energy regime are investigated. Extreme points of the configurational entropy provide the experimentally obtained cross sections within an optimal root-mean-square deviation.
