As reviewed in some detail in , at cosmic-ray energies (√s : 6 − 40 TeV) we can identify two distinct set of estimations, one represented by the results of the Fly’s Eye Collaboration together with those by the Akeno Collaboration , and other by the results of Gaisser, Sukhatme, Yodh (GSY) with those by Nikolaev .
On the total cross section extrapolations to cosmic-ray energies
Three techniques can be distinguished to determine the investigating unaccomproton-air cross section: panied hadrons by Yodh et al.
