1 99 6 MSW - like enhancements without matter
We study the effects of a scalar field, coupled only to neutrinos, on oscillations among weak interaction current eigenstates. The effect of a real scalar field appears as effective masses for the neutrino mass eigenstates, the same for ¯ ν as for ν. Under some conditions, this can lead to a vanishing of δm 2 , giving rise to MSW-like effects. We discuss some examples and show that it is possib...
متن کاملNeutrino 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 کاملThe MSW effect and Matter Effects in Neutrino Oscillations
The MSW (Mikheyev-Smirnov-Wolfenstein) effect is the adiabatic or partially adiabatic neutrino flavor conversion in medium with varying density. The main notions related to the effect, its dynamics and physical picture are reviewed. The large mixing MSW effect is realized inside the Sun providing the solution of the solar neutrino problem. The small mixing MSW effect driven by the 1-3 mixing ca...
متن کاملMSSM Dark Matter Without Prejudice
Recently we examined a large number of points in a 19-dimensional parameter subspace of the CP-conserving MSSM with Minimal Flavor Violation. We determined whether each of these points satisfied existing theoretical, experimental, and observational constraints. Here we discuss the properties of the parameter space points allowed by existing data that are relevant for dark matter searches.
متن کاملThe Msw Conversion of Solar Neutrinos and Random Matter Density Perturbations *
We present a generalization of the resonant neutrino conversion in matter, including a random component in the matter density profile. The study is focused on the effect of such matter perturbations upon both large and small mixing angle MSW solutions to the solar neutrino problem. This is carried out both for the active-active ν e → ν µ,τ as well as active-sterile ν e → ν s conversion channels...
