چکیده

Taking into account the stringent limits from helioseismology observations on possible matter density fluctuations described by magnetohydrodynamics theory, we find the corresponding time variations of solar neutrino survival probability due to the resonant spin-flavor precession phenomenon with amplitude of order O(10%). We discuss the physics potential of high statistics real time experiments, like as Superkamiokande, to observe the effects of such magnetohydrodynamics fluctuations on their data. We conclude that these observations could be thought as a test of the resonant spin-flavor precession solution to the solar neutrino anomaly. PACS numbers: 90.60.Jw, 96.60.Hv

MHD Solar Fluctuations and Solar Neutrinos

Assuming a non-vanishing magnetic moment of neutrinos, active electron neutrinos that are created in the Sun can interact with the solar magnetic field and be spin-flavor converted into sterile nonelectron neutrinos or into active nonelectron antineutrinos. This phenomenon is called Resonant Spin-Flavor Precession (RSFP). Particles resulting from RSFP interact with solar neutrino detectors sign...

On the Resonant Spin Flavor Precession of the Neutrino in the Sun

This work deals with the possible solution of the solar neutrino problem in the framework of the resonant neutrino spin-flavor precession scenario. The event rate results from the solar neutrino experiments as well as the recoil electron energy spectrum from SuperKamiokande are used to constrain the free parameters of the neutrino in this model (∆m2 and μν) . We consider two kinds of magnetic p...

J un 1 99 4 Neutrino Oscillations in Noisy Media

We develop the Redfield equation for delta-correlated gaussian noise and apply it to the case of two neutrino flavor or spin precession in the presence of a noisy matter density or magnetic field, respectively. The criteria under which physical fluctuations can be well approximated by the delta-correlated gaussian noise for the above cases are examined. Current limits on the possible neutrino m...

The Neutrino Magnetic Moment and Time Variations of the Solar Neutrino Flux

The present status of the neutrino magnetic moment solutions of the solar neutrino problem is summarized. After a brief review of the basics of the neutrino spin and spin–flavor precession I discuss the experimental data and show how the neutrino resonant spin–flavor precession (RSFP) mechanism can naturally account for sizeable time variations in the Homestake signal and no observable time var...
