Spin-flavor precession solution to the solar neutrino problem and magnetohydrodynamics spectrum in the Sun

We argue that solar neutrino observations have to be sensitive to the effects of magnetohydrodynamics fluctuations in the Sun if the resonant spin-flavor precession mechanism is the solution to the solar neutrino problem. We find that the required solar magnetic field for this solution presents global and localized magnetic waves with a typical period of the order of 1 to 10 days, which can generate a corresponding periodical time modulation of the solar neutrino observations. These effects can be thought of as a test to the spin-flavor precession solution. Periodicity of this order is not excluded by available experimental data although only with the high statistics of future real time experiments can a precise test be realized. We discuss also that these magnetic fluctuations can be used to obtain information about the structure of the magnetic field in the solar interior.
