Testing the Vacuum Oscillation and the Msw Solutions of the Solar Neutrino Problem
نویسنده
چکیده
Solar model independent tests of the vacuum oscillation and MSW solutions of the solar neutrino problem are considered. Detailed predictions for time (seasonal) variations of the signals in the future solar neutrino detectors (SNO, Super Kamiokande, BOREXINO, HELLAZ), if solar neutrinos take part in vacuum oscillations, are given. Results on the distortions of the spectra of 8B neutrinos, and of e from the reaction ν + e → ν + e induced by 8B neutrinos, in the cases of vacuum oscillations or MSW transitions are presented for a large number of values of the relevant parameters. The possibilities to distinguish between the vacuum oscillation, the MSW adiabatic, and the MSW nonadiabatic transitions (solutions) in the future solar neutrino experiments are discussed.

Status and prospects of MSW and vacuum oscillation solutions of the solar neutrino problem
The current interpretation of the solar neutrino problem in terms of MSW or vacuum oscillations depends signiicantly on the absolute neutrino uxes, i.e., on solar model calculations. However, second-generation experiments such as SuperKamiokande, SNO, and Borexino, will be able to test these neutrino oscillation solutions independently of solar models. We discuss the theoretical estimates and t...

متن کاملThe Simplest Resonant Spin–Flavour Solution to the Solar Neutrino Problem
We re-analyse the resonant spin–flavour (RSF) solutions to the solar neutrino problem in the framework of analytic solutions to the solar magneto-hydrodynamics (MHD) equations. By substantially eliminating the arbitrariness associated to the magnetic field profile due to both mathematical consistency and physical requirements we propose the simplest scheme (MHD-RSF, for short) for solar neutrin...
