Query: Particle Physics with High Energy Neutrinos   The topic of this review is the particle astrophysics of high energy
neutrinos. High energy is defined as $E_{\nu} > 100$~MeV. Main topics include:
-- atmospheric neutrinos and muons from $\pi$, $K$ and charm decay. They probe
uncharted territory in neutrino oscillations and constitute both the background
and calibration of high energy neutrino telescopes, -- sources of high energy
neutrino beams: the galactic plane, the sun, X-ray binaries, supernova remnants
and interactions of extra-galactic cosmic rays with background photons, -- an
extensive review of the mechanisms by which active galaxies may produce high
energy particle beams, -- high energy neutrino signatures of cold dark matter
and, -- a brief review of detection techniques (water and ice Cherenkov
detectors, surface detectors, radio- and acoustic detectors, horizontal
airshower arrays) and the instruments under construction.
