Abstract:
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.
