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.
