Solar Neutrinos
Present results and future measurements of solar neutrinos are discussed. The results to date indicate that solar electron neutrinos are changing to other active types and that transitions solely to sterile neutrinos are disfavored. The flux of 8 B solar neutrinos produced in the Sun, inferred assuming only active neutrino types, is found to be in very good agreement with solar model calculatio...
متن کاملSolar Neutrinos
Experimental work with solar neutrinos has illuminated the properties of neutrinos and tested models of how the sun produces its energy. Three experiments continue to take data, and at least seven are in various stages of planning or construction. In this review, the current experimental status is summarized, and future directions explored with a focus on the effects of a non-zero θ13 and the i...
متن کاملSolar neutrinos
Within the last decade solar neutrino physics has evolved into a field of relevance not only for probing our understanding of stellar physics, but also for investigating and pinpointing intrinsic neutrino properties, most importantly neutrino masses and mixing angles. To date, results from six different and partly complementary experiments have been acquired. Taken together, these experimental ...
متن کاملStandard Solar Neutrinos
We describe in detail an improved standard solar model which has been used to calculate the fluxes of standard solar neutrinos. It includes premain sequence evolution, element diffusion, partial ionization effects, and all the possible nuclear reactions between the main elements. It uses updated values for the initial solar element abundances, the solar age, the solar luminosity, the nuclear re...
متن کامل– 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...
