Extragalactic radiation and the ultra-high-energy cosmic-ray spectrum
Nature, 1989The effect of extragalactic microwave and submillimeter-radiation fields on the ultrahigh-energy cosmic-ray spectrum is reexamined. It is found that the general characteristics of the spectrum can be derived from fairly simple analytical arguments. It is shown that the various spectral features obtained by numerical calculations can be explored by ...

Probing interactions beyond the electroweak scale with ultra high energy cosmic radiation
AIP Conference Proceedings, 2001We demonstrate how current and future data on ultra-high energy cosmic rays and neutrinos can be used to probe new interactions at energies not or hardly accessible in accelerator experiments of the near future. As a specific example we discuss the possibility that neutrinos attain new interactions in the TeV range in particle physics models involving ...

A limit to the rate of ultra high energy γ-rays in the primary cosmic radiation
Astroparticle Physics, 1996Abstract An upper limit to the flux of Ultra High Energy (UHE) γ-rays in the primary cosmic radiation is obtained through the data of the electromagnetic and the muon detectors of the EAS-TOP Extensive Air Shower array (Campo Imperatore, National Gran Sasso Laboratories, atmospheric depth 810g cm−2). The search is performed by selecting Extensive Air

Interaction of ultra-high energy cosmic rays with microwave background radiation
Astrophysics and Space Science, 1990The formation of the ‘bump’ and the ‘black-body cutoff’ in the cosmic-ray (CR) spectrum arising from the π-meson photoproduction reaction in collisions of UHE CR protons with the microwave background radiation (MBR) is studied. A kinetic equation which describes CR proton propagation in the MBR with account of the catastrophic nature of the π-meson ...

Ultra-High Energy Cosmic Radiation: Current Issues and Future Prospects
AIP Conference Proceedings, 2010We briefly review the current experimental and theoretical status of cosmic radiation above ∼1017 eV, including secondary neutrinos and gamma‐rays. We focus on questions related to chemical composition and sky distributions of these particles as well as on the location and nature of their sources.

Probing physics and astrophysics at extreme energies with ultra high energy cosmic radiation
AIP Conference Proceedings, 2001The highest energy cosmic rays observed possess macroscopic energies and their origin is likely to be associated with the most energetic processes in the Universe. Their existence triggered a flurry of theoretical explanations ranging from conventional shock acceleration to particle physics beyond the Standard Model and processes taking place at the ...
