Physics of Extremely High Energy Cosmic Rays
Over the last third of the century, a few tens of events, detected by ground-based cosmic ray detectors, have opened a new window in the field of high-energy astrophysics. These events have macroscopic energies exceeding 5 × 10 eV -, unobserved sources if supposed to be in our vicinity -, an unknown chemical composition and a production and transport mechanism yet to be explained. With a flux a...
متن کاملUltra-high energy cosmic rays and new physics
Cosmic rays with energies beyond the Greisen-Zatsepin-Kuzmin ‘cutoff’ at ∼ 4 × 10 GeV pose a conundrum, the solution of which requires either drastic revision of our astrophysical understanding, or new physics beyond the Standard Model. Nucleons of such energies must originate within the local supercluster in order to avoid excessive energy losses through photopion production on the cosmic micr...
متن کاملHigh energy cosmic rays
I review here some of the physics we are learning and expect to learn in the near future through the observation of cosmic rays. The study of cosmic rays involves a combination of data from accelerators, ground arrays, atmospheric fluorescence detectors and balloon and satellite experiments. I will discuss the data of the Pierre Auger Observatory, PAMELA, ATIC and FST among other experiments.
متن کاملNew physics from ultrahigh energy cosmic rays
Observations of cosmic rays with energies above ∼ 4 × 10 GeV have inspired several speculative suggestions concerning their origin. The crucial question is whether or not the spectrum exhibits the expected ‘GZK cutoff’ at this energy — concerning which there are presently contradictory results. If there is indeed a cutoff, then the sources are cosmologically distant and rather exotic in nature....
