New physics from ultrahigh energy cosmic rays

ACTA PHYS POL B 35:1 (2004) 351-364

Abstract:

Observations of cosmic rays with energies above similar to 4 x 10(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. If there is no cutoff then new physics is required.
