Review of Low Energy Neutrinos
Some issues regarding low energy neutrinos are reviewed. We focus on three aspects i)We show that by employing very low energy (a few keV) electron neutrinos, neutrino disappearance oscillations can be investigated by detecting recoiling electrons with low threshold spherical gaseous TPC’s. In such an experiment, which is sensitive to the small mixing angle θ13, the novel feature is that the os...
متن کاملLow-energy Anti-neutrinos from the Sun
We consider the sensitivity of future neutrino experiments in the low energy region, such as BOREXINO or HELLAZ, to a solar ν̄e signal. We show that, if neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes, then a new opportunity arises to observe the ν̄e’s and thus to probe the Majorana nature of the neutrinos. This is achieved by comparing the slop...
متن کاملOscillations of very low energy atmospheric neutrinos
There are several new features in production, oscillations and detection of the atmospheric neutrinos of low energies, E < ∼ 100 MeV. The flavor ratio, r, of muon to electron neutrino fluxes is substantially smaller than 2 and decreases with energy, significant part of events is due to the decay of invisible muons at rest, etc. Oscillations in two-layer medium (atmosphere earth) should be taken...
متن کاملNew Tests for Neutrinos in Low-energy Solar Experiments
We show how future solar neutrino experiments in the low energy region can be used to test novel neutrino properties. Information on the Majorana nature or neutrino magnetic moments can be extracted from the observation of electron anti-neutrinos from the Sun and the measurement of an azimuthal asymmetry in the total number of events, respectively. 1. Low-energy electron Anti-neutrinos from the...
متن کاملSpectroscopy of Low Energy Neutrinos from the Sun
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...
