A Natural Explanation of All Solar Neutrino Data by Resonant Spin-Flavor Precession Scenario

It is emphasized that the $E_{\nu }$ (neutrino energy) spectrum of the ${\nu }_e$ survival probability in the Resonant Spin-Flavor Precession (RSFP) scenario has very desirable shape to reconcile all existing solar neutrino data. As the result, the RSFP scenario is shown to have rather broad allowed region to reconcile the data in the ($B,\mathrm{\Delta }{m}^2$) plane, with $B$ being the magnetic field strength inside the Sun. The sensitivity of the allowed region on the different choices of the $B$ profile, and the time variations of the solar neutrino event rates in the RSFP scenario are also discussed in some detail.
