We construct and apply to decays a truly neutral local quantum field that is entirely based upon momentum space Majorana spinors. We make the observation that theory with momentum space Majorana spinors of real C parities is equivalent to Dirac’s theory. For imaginary C parities, the neutrino mass can drop out from the single decay trace and reappear in , a curious and in principle experimentally testable signature for a non-trivial impact of Majorana framework in polarization experiments.
