Can we distinguish Majorana and Dirac neutrinos in solar neutrino experiments ?

Abstract

If neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes then a new opportunity to distinguish Majorana and Dirac neutrinos by measuring the differential νee-scattering cross section in solar neutrino detectors arises. The experiment like HELLAZ would be preferable in testing of recoil electron spectra differences initiated by Majorana and Dirac neutrinos since low energy recoil electrons (T≥ 100 keV) can be detected and electron energy and direction can be determined with good precision.
