On the indistinguishability of Majorana-from Dirac-neutrino propagation in a stellar medium

  • S. Esposito


We study, in the framework of the Standard Model, the propagation of (pure) Majorana neutrinos in a typical stellar medium and show that Majorananeutrino matter oscillations are completely indistinguishable from Dirac ones’, even if in the case of no family mixing Majorana neutrinos can be distinguished from Dirac ones in the non-relativistic limit. Moreover, ifCP violation is present, an effective phase arises in the effective mixing matrix but, due to a symmetry of the Majorana fields, this cannot be univocally determined.
