Neutrino oscillations and the solar-neutrino problem

Physical Review D, 1987
The values of neutrino masses and mixing angles which are required by the Mikheyev-Smirnov-Wolfenstein (MSW) solution to the solar-neutrino problem are found from analytic solutions to the neutrino propagation equations in the Sun. They coincide with those obtained through extensive numerical computations by Rosen and Gelb.

Solar-neutrino experiments

Physical Review Letters, 1989
The observation of solar neutrinos at Kamiokande rules out the Mikheyev-Smirnov-Wolfenstein (MSW) theory with a large'' mass difference between the neutrinos, {Delta}{ital m}{sup 2}{congruent}10{sup {minus}4} eV{sup 2}. There remain the MSW theory with a small {Delta}{ital m}{sup 2}{congruent}10{sup {minus}7} eV{sup 2} or the assumption of unexpectedly

Solar neutrino observations and neutrino oscillations

Physical Review D, 1990
The results of recent Kamiokande-II and {sup 37}Cl solar-neutrino experiments are quantitatively analyzed assuming the Mikheyev-Smirnov-Wolfenstein solution to the solar-neutrino problem. It is found that the parameter region known as the large mass'' solution to the solar-neutrino problem is disfavored by a little more than 1 {sigma} while the small ...

The solar neutrinos

AIP Conference Proceedings, 1978
We discuss the current model based on a few hypotheses advanced to explain the missing solar neutrino. None of these hypotheses seems to be very satisfactory. We propose a new model of a neutrinoless fusion process in the solar interior.

Neutrino Oscillations and Solar Neutrinos

Physics Today, 1989
The neutrino is the elementary particle postulated by Wolfgang Pauli to account for the apparent nonconservation of energy in nuclear beta decay. Neutrinos are now believed to exist in at least three varieties, or “flavors,” labeled νe, νμ and ντ and distinguished by the way they interact. There are also three antineutrinos, ν̄e, ν̄μ and ν̄τ.

Solar neutrinos

Resonance, 1999
The standard solar model with the standard electroweak theory does not explain the solar neutrino problem. However, a slight modification to this theory, in which there is a mass difference in the neutrinos and mixing between them, does seem to explain the experimental observations.

Solar Neutrino Measurements

2018
We present the most recent results from the two currently running solar neutrino experiments, Borexino at the Gran Sasso laboratory in Italy and SuperK at Kamioka mine in Japan. SuperK has released the most precise yet measurement of the 8B solar neutrino interaction rate, with a precision better than 2\%, consistent with a constant solar neutrino ...

Solar Neutrinos — Cosmological Neutrinos

1977
A review of the solar neutrino puzzle (contradiction between theory and observation) is given. Some possible explanations are discussed critically. — The neutrino flux of cosmological origin (Big Bang) has been estimated. The possibility of observing relic neutrinos with the help of their gravitational effects is discussed.
