Radio Detection of Ultrahigh Energy Neutrinos

There are several models that predict the existence of ultrahigh energy (UHE) neutrinos. No man-made machines, existing or planned, can produce any particles at these energies. It is the energies of these neutrinos that make them very interesting for the particle physics and astrophysics community; these neutrinos can be a unique tool to study the unknown regimes of energy, space, and time. No wonder there is intense experimental activity focused on the detection of these neutrinos. UHE neutrinos have not been observed in any experiment so far. However, most of the UHE neutrino flux models predict that the fluxes of these neutrinos are too small to be observable in the existing detectors. Therefore, more powerful detectors are being built and we are
at the beginning of a new and exciting era in neutrino astronomy. My focus will be on the radio detection of ultrahigh energy neutrinos; I will use RICE (Radio Ice Cherenkov Experiment) as an example.
