Abstract
We study, in the framemork of the Standard Model, the propagation of (pure) Majorana neutrinos in a typical stellar medium and show that Majorana-neutrino 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, if CP 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
