Solar Neutrinos: Expecting 1996 *

چکیده

These are remarks (mainly on the solar neutrinos) written in anticipation of 1996-the year which can be crucial for the neutrino physics. Recent results on solar neutrinos are discussed. The topics include: (solar) model independent approach to the solar neutrino problem, status of different solutions of the problem, standard and non-standard scenarios of the lepton mixing, light singlet fermions and the neutrino phenomenology.

Possible tests for sterile neutrinos ∗

It is shown that the future SNO and Super-Kamiokande experiments, in which high energy 8 B neutrinos will be detected through the observation of CC, NC and ν–e elastic scattering processes, could allow to reveal in a model independent way the presence of sterile neutrinos in the flux of solar neutrinos on the earth.

Neutrino Mass in Physics and Astrophysics

The symmetry between quarks and leptons suggests that neutrinos should have mass. As embodied in the grand unified theory SO(10) this yields masses that can only be detected by neutrino oscillations. Such oscillations could be very important for supernova physics. Present observations of solar neutrinos when combined with standard solar model calculations imply particular parameters for neutrin...

Possible tests of neutrino maximal mixing and comments on matter effects

We show in a simple and general way that matter effects do not contribute to the averaged value of the probabilities of transition of solar νe’s into other states in the case of maximal mixing of any number of massive neutrinos. We also show that future solar neutrino experiments (Super-Kamiokande and SNO) will allow to test the model with maximal mixing of three massive neutrinos in a way that...

– 1 – Solar Neutrinos

The Sun is a main-sequence star at a stage of stable hydrogen burning. It produces an intense flux of electron neutrinos as a consequence of nuclear fusion reactions which generate solar energy, and whose combined effect is 4p + 2e − → 4 He + 2ν e + 26.73 MeV − E ν , (1) where E ν represents the energy taken away by neutrinos, with an average value being E ν ∼ 0.6 MeV. Each neutrino-producing r...

Fourier spectrum analysis of the new solar neutrino capture rate data for the Homestake experiment

All four solar neutrino experiments (Homestake, Kamiokande, GALLEX, SAGE) observe a deficit of solar neutrinos compared to the predictions of the Standard Solar Model. Additionally, any two of the three classes of solar neutrino experiments indicate that the largest suppression is in the middle of the solar neutrino spectrum (the Be-7 line and the lower part of the B-8 spectrum)[1]. Among these...
