On the resonant spin flavor precession of the neutrino in the sun

This work deals with the possible solution of the solar neutrino problem in the framework of the resonant neutrino spin-flavor precession scenario. Th e event rate results from the solar neutrino experiments as well as the rec oil electron energy spectrum from SuperKamiokande are used to constrain the free parameters of the neutrino in this model (Deltam(2) and mu (nu)) We c onsider two kinds of magnetic profiles inside the sun. For both cases, a st atic and a twisting field are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
