Nonextensive statistics in stellar plasma and solar neutrinos
Nonextensive and quantum uncertainty effects (related to the quasiparticles composing the stellar core) have strong influence on the nuclear rates and, of course, affect solar neutrino fluxes. Both effects do coexist and are due to the frequent collisions among the ions. The weakly nonextensive nature of the solar core is confirmed. The range of predictions for the neutrino fluxes is enlarged a...
متن کاملSolar 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 کاملThe Solar Core and Solar Neutrinos
The solar neutrino problem has nagged physicists for over 30 years and, for most of us, has a natural solution in neutrino oscillations, either in vacuo or matter-enhanced (MSW effect). This modification of neutrino properties (with mν <∼ 10−2 eV and mixing ∼ 0.001–1) requires an extension of the Standard Model not detectable in accelerators and consistent with many models of unification. 1 But...
