Beta decays with momentum space Majorana spinors Article uri icon

abstract

  • We construct and apply to β 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%27s theory. For imaginary C parities, the neutrino mass can drop out from the single-β decay trace and reappear in 0νββ, a curious and in principle experimentally testable signature for a non-trivial impact of Majorana framework in polarization experiments. © Società Italiana di Fisica/Springer-Verlag 2004.
