Unusual events in PeV energy cosmic rays and their possible interpretation

摘要

Unusual events observed in hadron and muon experiments and some EAS characteristics, which cannot be explained in the frame of existing theoretical models and approaches, are considered. Some ideas about new physical process inclusion at PeV energies are described. A possibility of explanation of all unusual experimental results in the frame of new physics is analyzed. Perspectives to check these new ideas and consequences for experiments at higher energies are discussed.
