There are several models that predict the
existence of high and ultrahigh energy (UHE)
neutrinos; neutrinos that have amazingly high
energies--- energies above 10^{15}eV. No
man-made machine, 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. Consequently, there is
intense experimental activity focused on the
detection of neutrinos; no UHE neutrinos have
been detected by these experiments so far.
However, most of the UHE neutrinos flux models
predict that the fluxes of these neutrinos might
be too small to be detected by the current
detectors. Therefore, more powerful detectors
are being built and we are at the beginning of a
new and exciting era in neutrino astronomy.
Focus will be on the radio detection of
ultrahigh energy neutrinos. |
