Majorana versus Dirac neutrino in v — e scattering process and its possible applications

In previous works it was established that if neutrino helicity differs from minus one, then the Dirac and Majorana cross sections in neutrino-electron scattering are different, despite of the smallness of the neutrino mass. Considering this fact, it is possible to employ that difference in order to establish a method to derive an upper bound for neutrino magnetic moment.
