Neutrino decay and solar neutrino seasonal effect [PDF]
Physics Letters B, 2016 We consider the possibility of solar neutrino decay as a sub-leading effect on their propagation between production and detection. Using current oscillation data, we set a new lower bound to the ν2 neutrino lifetime at τ2/m2≥7.2×10−4s.eV−1 at 99% C.L ...

Invisible Labor and the "Ghost Particle": Underground Physics at the Kolar Gold Fields. [PDF]
Ber WissAbstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Advances in High Energy Physics, 2013 The study of solar neutrinos has given a fundamental contribution both to astroparticle and to elementary particle physics, offering an ideal test of solar models and offering at the same time relevant indications on the fundamental interactions among particles.

The Future of Solar Neutrinos [PDF]
Annual Review of Nuclear and Particle Science, 2021 In this article we review the current state of the field of solar neutrinos, including flavor oscillations, nonstandard effects, solar models, cross section measurements, and the broad experimental program thus motivated and enabled. We describe the historical discoveries that contributed to current knowledge, and define critical open questions to be ...

Neutrino masses and solar neutrinos [PDF]
Physical Review D, 1992 It has been pointed out by Bahcall and Bethe and others that all solar-neutrino data can be explained by Mikheyev-Smirnov-Wolfenstein oscillations with $m({\ensuremath{\nu}}_{\ensuremath{\mu}})\ensuremath{\sim}{10}^{\ensuremath{-}3}$ eV consistent with ideas of grand unified theories (GUT's).

AIP Conference Proceedings, 1966 The predicted capture rate in the Cl37 experiment for detecting solar neutrinos is calculated using the results of recent nuclear experiments and solar-model investigations. It is shown that additional experiments (e.g., with H2, Li7, B11, or ν-e scattering) are necessary to establish the relative contributions of the proton-proton chain and the CNO ...

Spectroscopy of solar neutrinos [PDF]
Astronomische Nachrichten, 2010 AbstractIn the last years, liquid‐scintillator detectors have opened a new window for the observation of low‐energetic astrophysical neutrino sources. In 2007, the solar neutrino experiment Borexino began its data‐taking in the Gran Sasso underground laboratory.

Physics Letters B, 1994 We re-examine the neutrino decay solution to the solar neutrino problem in light of the new data from Gallex II and Kamiokande III. We compare the experimental data with the solar models of Bahcall and Pinsonneault and Turck-Chieze and find that neutrino decay is ruled out as a solution to the solar neutrino problem at better than the 98\% c.l.
