The cross sections of neutrino-nucleon scattering at high energies are evaluated with quark masses at next-to-leading order in strong interaction corrections. We compare the results with two kinds of schemes for treating the heavy quarks, the fixed flavor number scheme and the variable flavor number scheme for muon neutrinonucleon interaction, and discuss which scheme is more relevant. The opti...

We study the role that the future detection of the neutrino burst from a galactic supernova can play in the reconstruction of the neutrino mass spectrum. We consider all possible 3ν mass and flavor spectra which describe the solar and atmospheric neutrino data. For each of these spectra we find the observable effects of the supernova neutrino conversions both in the matter of the star and the e...

The relic neutrinos are expected to acquire a bulk relative velocity with respect to the dark matter at low redshifts, and neutrino wakes are expected to develop downstream of the dark matter halos. We propose a method of measuring the neutrino mass based on this mechanism. This neutrino wake will cause a dipole distortion of the galaxy-galaxy lensing pattern. This effect could be detected by c...

A new facility to measure neutrino mass differences and mixing angles and neutrino–nucleus cross sections, such as the proposed ORLaND facility at Oak Ridge, would contribute to the experimental determination of vacuum mixing parameters and would provide an experimental foundation for the many neutrino– nucleus weak interaction rates needed in supernova models. This would enable more realistic ...

Core collapse supernovae are a huge source of all flavor neutrinos. The flavor composition, energy spectrum and time structure of the neutrino burst from a galactic supernova can provide information about the explosion mechanism and the mechanisms of proto neutron star cooling. Such data can also give information about the intrinsic properties of the neutrino such as flavor oscillations. One im...

The investigation of the problem of neutrino masses and mixing is the central theme of today’s neutrino physics. This problem is very important for elementary particle physics. There is a general belief that its investigation is a way to discover new physics. The problem of the masses of the neutrinos has also an exceptional importance for astrophysics. If the neutrino masses are in the eV regi...

Measurements of CP–violating observables in neutrino oscillation experiments have been studied in the literature as a way to determine the CP– violating phase in the mixing matrix for leptons. Here we show that such observables also probe new neutrino interactions in the production or detection processes. Genuine CP violation and fake CP violation due to matter effects are sensitive to the imag...

Limits on ν µ → ν τ oscillations and tau neutrino magnetic moment from neutrino-electron scattering Abstract If the tau neutrino has large magnetic moment it might be effectively used to search for ν µ −ν τ neutrino oscillations in neutrino-electron scattering in beam dump experiments. Using the present experimental limits on the magnetic moments of tau and muon neutrinos, limit on the probabil...
