Previous calculations of photon-neutrino scattering in a constant background magnetic field are extended and corrected.

Accumulation and annihilation of weakly interacting massive particles (WIMPs) in the earth and the sun may be observed by the resulting neutrino signal. We demonstrate that, for certain parts of the SUSY parameter space, present and future neutrino telescopes can expect a higher rate of events due to tau-neutrinos than due to muon-neutrinos. We show how neutrino-oscillation, and in the case of ...

If neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes then a new opportunity to distinguish Majorana and Dirac neutrinos by measuring the differential ν e e-scattering cross section in solar neutrino detectors arises. The experiment like HELLAZ would be preferable in testing of recoil electron spectra differences initiated by Majorana and Dirac n...

The construction of a high energy (∼100 GeV), sign-selected neutrino beam opens exciting opportunities to search for beyond-standard-model physics as well as to make valuable QCDmeasurements. Such a beam can be produced at the Tevatron or, potentially, at the CERN SPS+. The resulting physics would be unique and complementary to the present neutrino program. Here we use neutrino-electron scatter...

Two methods are discussed for the solar neutrino spectroscopy in the sub-MeV region: absorption in a loaded liquid scintillator and elastic scattering in a TPC. The different neutrino oscillation solutions predict a strong effect in this energy region where the largest fraction (∼98%) of solar neutrinos lies. Both projects have reached the stage where they have to prove their capability to atta...

The sources of very high energy cosmic rays should also be sources of neutrinos. While the complete scheme of ultrahigh energy cosmic ray production is not yet understood [1], ancillary to cosmic ray production are neutrino fluxes, both at the source of the cosmic rays and through cosmic ray propagation and scattering with the microwave background. Given that neutrinos are unabsorbed and undefl...
