The Energy Frontier in Nature: Highest Energy Cosmic Radiation
Abstract content
Cosmic rays have been observed up to several 10^20 eV through the showers of secondary particles they induce in the atmosphere. Their existence poses formidable challenges and exciting prospects at the same time: Their origin and sources have not been identified yet, but they already allow to test physics at center of mass energies unattained in the laboratory, albeit in a rather indirect way. We will give an overview over the current situation, open questions and future prospects, including the role of secondary gamma-rays and neutrinos produced in interactions of charged primary cosmic rays.
