Possible explanation of results of CR investigations in the energy interval 1015 – 1017 eV: Nuclear-physical approach

Abstract

Among three possible approaches to explanation of the behaviour of CR energy spectrum and mass composition in the energy interval 1015 – 1017 eV: methodical, cosmophysical and nuclear-physical, the last of them is considered. A possibility of a new massive state of matter generation in interactions of CR with such energies is discussed. As a possible version, the production of blobs of quark-gluon plasma with a large orbital momentum is considered.
