On Radio Detection of Ultra-High Energy Neutrinos in Antarctic Ice
Interactions of ultrahigh energy neutrinos of cosmological origin in large
volumes of dense, radio-transparent media can be detected via coherent
Cherenkov emission from accompanying electromagnetic showers. Antarctic ice
meets the requirements for an efficient detection medium for a radio frequency
neutrino telescope. We carefully estimate the sensitivity of realistic antennas
embedded deep in the ice to 100 MHz - 1 GHz signals generated by predicted
neutrino fluxes from active galactic nuclei. Our main conclusion is that a {\it
single radio receiver} can probe a volume for events with
primary energy near 2 PeV and that the total number of events registered would
be roughly 200 to 400 in our most conservative estimate. An
array of such receivers would increase sensitivity dramatically. A radio
neutrino telescope could directly observe and test our understanding of the
most powerful particle accelerators in the universe, simultaneously testing the
standard theory of particle physics at unprecedented energies.Comment: 45 pages, 21 figures, uuencoded, gzipped, submitted to Phys. Rev. D,
