Abstract.

We construct and apply to \(\beta \) 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 \(\beta \) decay trace and reappear in \(0\nu \beta\beta \), a curious and in principle experimentally testable signature for a non-trivial impact of Majorana framework in polarization experiments.
