Hadron interactions in cosmic rays at energies above the accelerator range

Experimental data on inelastic collisions of nucleons, pions, and nuclei in the energy range 1--106 TeV have been used for analysis of the dependence of the multiple production of hadrons on the energy of the incident hadron. The general pattern of inelastic hadron collisions is characterized by approximate scale invariance in the energy region 1--100 TeV and by a significant difference of the multiple-production process from that observed at accelerator energies in a number of the mean parameters, such as the multiplicities and composition of the secondary particles and their transverse momenta
