Neutrino properties beyond the minimal standard electroweak model are Super-Kamiokande, SNO, Borexino and HELLAZ will be able to establish that Only future observations of spectral distortions, or terrestrial modulation orįlavor change of solar neutrinos in solar neutrino experiments, such as Rates, radiation transport and particle diffusion in dense stellar plasmas. Results from those predicted by the standard solar models may reflect theĪpproximate nature of of solar models and of our knowledge of nuclear reaction Neutrino problem does not provide conclusive evidence for neutrino propertiesīeyond the standard electroweak model. Since neither a flavor change, nor a terrestrial variation, nor a spectralĭistortion of the $^8$B solar neutrino flux has been observed yet, the solar This can beĮxplained by neutrino oscillations and the Mikheyev-Smirnov-Wolfenstein effect. Pep, $^7$Be and NO solar neutrino fluxes are strongly suppressed. This problem has puzzled scientists for over three decades, but there may finally be a possible solution. It is the discrepancy between the number of neutrinos predicted by the Standard Solar Model, and the number of neutrinos observed coming from the Sun. Measurements of Super-Kamiokande, SAGE and GALLEX suggest that the expected the The solar neutrino problem is a long-standing puzzle in astrophysics. Recent measurements of nuclear fusion cross sections at low energies. Solar model of Dar and Shaviv with nuclear reaction rates that are supported by Solar neutrino flux is in good agreement with that predicted by the standard With the minimal signal expected from the solar luminosity.
