Abstract

In the framework of eikonalized mini-jet model, contributions from gluon recombination effects are studied for the free proton in pp and $\overline{p}p$ 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 can shed new light on some features of specific models of nuclear reactions, which are described by the corresponding reaction cross section, providing the latter by the necessary model parameters within an optimal root-mean-square deviation.
