Neutrino Oscillations and the MSW effect in Random Solar Matter
We investigate the effects of random density fluctuations on neutrino oscillations in the Sun environment. We show how the average of certain quantities which can be used to describe the MSW effect can be computed analytically. We examine also the hypothesis commonly accepted that only perturbations inside the resonance layer can have relevance. The average amplitud, which gives the ”coherent p...
متن کاملHelioseismology, Msw and the Solar Neutrino Problem
In this talk I summarize recent work done in collaboration with Cliff Burgess and Denis Michaud , in which we performed a detailed investigation of how solar neutrinos propagate through helioseismic waves. We find that the MSW solar neutrino spectrum is not modified at all in the presence of seismic waves. This finding differs from earlier estimates mainly because most helioseismic waves are to...
متن کاملSolar model uncertainties, MSW analysis, and future solar neutrino experiments.
Various theoretical uncertainties in the standard solar model and in the Mikheyev-Smirnov-Wolfenstein (MSW) analysis are discussed. It is shown that two methods of estimating the solar neutrino flux uncertainties are equivalent: (a) a simple parametrization of the uncertainties using the core temperature and the nuclear production cross sections; (b) the Monte Carlo method of Bahcall and Ulrich...
متن کاملThe Super - Kamiokande Day - Night Effect Data and the MSW Solutions of the Solar Neutrino Problem
The current Super-Kamiokande data on the D-N asymmetry between the the day event rate and the Night and Core event rates, produced by solar neu-trinos which respectively cross the Earth along any trajectory and cross the Earth core before reaching the detector, imply rather stringent constraints on the MSW small mixing angle (SMA) ν e → ν µ(τ) solution of the solar neutrino problem. A simplifie...
متن کاملMSW mediated neutrino decay and the solar neutrino problem
We investigate the solar neutrino problem assuming simultaneous presence of MSW transitions in the sun and neutrino decay on the way from sun to earth. We do a global χ-analysis of the data on total rates in Cl, Ga and Superkamiokande (SK) experiments and the SK day-night spectrum data and determine the changes in the allowed region in the ∆m − tan θ plane in presence of decay. We also discuss ...
