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

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 vee scattering cross section in solar neutrino detectors arises. An experiment like HELLAZ would be preferable in testing recoil electron spectra differences initiated by Majorana and Dirac neutrinos since low-energy recoil electrons (T ⩾ 100 keV) can be detected and the electron energy and direction can be determined with good precision.
