Abstract
As a possible explanation of the solar neutrino puzzle, several authors have invoked a neutrino helicity rotation (vL → vR) in the solar magnetic field, coupled to a neutrino magnetic moment. We discuss: (i) the effect on the vL → vR conversion probability of the different coherent interaction with matter of the two neutrino helicity states; (ii) the azimuthal asymmetry in the elastic v-e scattering of solar neutrinos, due to the interference between the weak and the electromagnetic amplitude. We also briefly comment on the theoretical problem posed by a neutrino magnetic moment as large as 10-10μB. © 1988.File in questo prodotto:
