Hi,(adsbygoogle = window.adsbygoogle || []).push({});

We know that when we have one flavour of neutrino, it can change into another flavour by neutrino oscillations. However, if we consider a mass eigenstate, then is it true that it can never change into a different mass eigenstate? In other words is a [itex]|v_{1}>[/itex] neutrino forever a [itex]|v_{1}>[/itex]? I think the answer is yes but I would like to clarify.

If so, are the mass eigenstates the "real" fundamental particles then but it just happens to be that we can only observe neutrino flavours?

Thank you!
