Elastic e- scattering of solar neutrinos with electromagnetic moments
Abstract
We consider the azimuthal asymmetry of the recoil electrons in elastic e- scattering of solar neutrinos, which can arise if neutrinos have electromagnetic moments and there is a large solar magnetic field. We show that using this effect it is not possible to distinguish between magnetic and electric dipole moment in the 1-Dirac and 2-Majorana neutrino cases and that averaging over neutrino energy is important and suppresses the azimuthal asymmetry in the 2-Majorana case.
