Abstract
Consequences of parametric resonances on neutrino resonant spin-flavor precession (RSFP) arising from global magnetohydrodynamic waves in the Sun are investigated. We show that for typical magnetic field profiles which generate an RSFP solution to the solar neutrino anomaly, the effects of the parametric resonance can be found for neutrinos of which the energy is of order 0.1 to 1MeV. This opens the possibility of investigating these effects using real time experiments, like Borexino or Hellaz.
