Solar magnetohydrodynamic modes and parametric resonance in neutrino spin–flavor conversion

MHD solar fluctuations and solar neutrinos

“…The global modes [9,10] obtained with the magnetic fields given by equations (12), (13) and (14), used in the analysis of the effect of localized modes, are very similar to each other. So, we present the effect of these modes on the neutrino RSFP phenomenon for just one of these magnetic fields, that we consider a good representative of the others:…”

“…These low energy neutrinos are the most abundant solar neutrinos, and the prediction of their flux is the one which carries less uncertainty, because of the correlation of these neutrinos with the solar luminosity. Since the MHD fluctuations we found in [9] appear to be affecting neutrinos with an energy range of the order of the pp-neutrinos energy, maybe Hellaz and/or Heron would be able to feel the time fluctuations on the neutrino signal generated by the MHD fluctuations.…”

“…MHD affects both the magnetic field profile as well as the matter density and therefore its effects will strongly influence the RSFP neutrino survival probability. Indeed we believe that such consequences can be thought as a test to this solution to the solar neutrino problem based on the RSFP mechanism [7][8][9][10].…”
