The Highest Energy Cosmic Rays and Neutrinos
James Beatty
Ohio State University
Cosmic rays have been observed with energies of tens of joules.
At these energies particles are attenuated by interactions with
the cosmic microwave background radiation, and must come from
nearby. The resulting feature in the cosmic ray spectrum has
been observed, and cosmic rays above this energy are anisotropic.
Neutrinos produced in the interaction of cosmic rays with the
microwave background can be detected by radio techniques from
high altitude balloons viewing the Antarctic ice sheet. I will
discuss the status of these cosmic ray observations and of
efforts to detect these neutrinos.
