Neutrino Oscillations in the Solar Noisy Matter and Magnetic Field

Abstract

Solar neutrino oscillations as a probe for the magnetic fields and matter density fluctuations in the solar interior as well as for the neutrino electromagnetic properties are discussed. The analysis of neutrino oscillations in the framework of the neutrino spin‐flavor conversion in the convective zone magnetic fields as a sub‐leading effect to the main LMA MSW oscillations could give the constraints to neutrino transition magnetic moment and magnetic field amplitude. We present the sensitivity of solar neutrino oscillations to the strength of the matter density perturbations given for the current experimental data and for future KamLAND result. The likely mechanism to generate the density noise based on the resonance between helioseismic and Alfven waves is pointed.
