Vetoing atmospheric neutrinos in a high energy neutrino telescope
We discuss the possibility to suppress downward atmospheric neutrinos in a
high energy neutrino telescope. This can be achieved by vetoing the muon which
is produced by the same parent meson decaying in the atmosphere. In principle,
atmospheric neutrinos with energies TeV and zenith angle up to 60
degree can be vetoed with an efficiency of > 99%. Practical realization will
depend on the depth of the neutrino telescope, on the muon veto efficiency and
on the ability to identify downward moving neutrinos with a good energy
estimation.Comment: 10 pages, 3 figures, accepted for publication in Physical Review
Recent s from IceCube
IceCube is a 1 km neutrino detector now being built at the South Pole.
Its 4800 optical modules will detect Cherenkov radiation from charged particles
produced in neutrino interactions. IceCube will search for neutrinos of
astrophysical origin, with energies from 100 GeV up to eV. It will be
able to separate , and . In addition to detecting
astrophysical neutrinos, IceCube will also search for neutrinos from WIMP
annihilation in the Sun and the Earth, look for low-energy (10 MeV) neutrinos
from supernovae, and search for a host of exotic signatures. With the
associated IceTop surface air shower array, it will study cosmic-ray air
showers.
IceCube construction is now 50% complete. After presenting preliminary
results from the partial detector, I will discuss IceCube's future plans.Comment: Invited talk presented at Neutrino 2008; 7 page
