Oscillation Solutions to Solar Neutrino Problem ∗
The current status of oscillation solutions to the Solar Neutrino Problem is reviewed. Four oscillation solutions are discussed in the light of 708d Superkamiokande data: MSW, Just-So VO, VO with Energy-Independent Suppression (EIS) and Resonant-Spin-Flavor-Precession (RSFP). Only EIS VO is strongly disfavoured by the global rates, mostly due to the Homestake data. Vacuum oscillations give an i...
متن کاملVEP oscillation solutions to the solar neutrino problem
We study the solar neutrino problem within the framework of a parametrized post-Newtonian formulation for the gravitational interaction of the neutrinos, which incorporates a violation to the equivalence principle (VEP). Using the current data on the rates and the energy spectrum we find two possible oscillation solutions, both for a large mixing angle. One of them involves the MSW effect in ma...
متن کاملOn the vacuum oscillation solutions of the solar neutrino problem.
We study the stability of the two–neutrino vacuum oscillation solution of the solar neutrino problem with respect to changes of the total fluxes of 8B and 7Be neutrinos, ΦB and ΦBe. For any value of ΦBe from the interval 0.7Φ BP Be ≤ ΦBe ≤ 1.3Φ BP Be the solar νe oscillations into an active neutrino, νe ↔ νμ(τ), provide at 95% C.L. a description of the existing solar neutrino data for ΦB ∼= (0....
متن کاملMaximal neutrino oscillation solution to the solar neutrino problem
We discuss a simple predictive solution to the solar neutrino problem based on maximal vacuum neutrino oscillations. The solution can be motivated by the exact parity symmetric model which predicts that the neutrino mass eigenstates are maximal mixtures of ordinary and mirror weak eigen-states (if neutrinos are massive). We show that this proposed solution to the solar neutrino problem is in re...
متن کاملNew Matter Effects in Neutrino Oscillation Experiments
Consequences of a new force mediated by a light scalar particle for neutrino oscillation experiments are considered. Such a force could give rise to neutrino masses and mixings whose matter dependence is much more significant than the MSW effect. We consider the effects of such a new force on the limits derived from oscillation experiments, and examine how the constraints on neutrino models are...
