Resumo
In this paper we use an eikonalized minijet model where the effects of the first nonlinear corrections to the DGLAP equations are taken into account. The contributions coming from gluon recombination effects are included in the DGLAP+GLRMQ approach for the free proton in the context of saturation models. The parameters of the model are fixed to fit total pp and p̄p cross sections, including the very recent data from LHC, HiRes, and Pierre Auger collaborations. Glauber and multiple scattering approximations are then used to describe the inclusive inelastic proton-Air cross section. Photoproduction cross sections, without change of parameters fixed before, are also obtained from the model using vector meson dominance and the additive quark model. We show and discuss our main results as well as the implications of saturation effects in the behavior of total hadronic and photonic cross sections at very high energies. © 2013 American Physical Society.
