| May 18, 2017 at 5:33 | comment | added | user12262 | Cosmas Zachos: "so $\nu_1, \nu_2$ are not the actual physical mass eigenstates $\nu_1, \nu_2$ of today's neutrino experiments" -- First of all, I'd find it better to make this distinction manifest by using suitably distinct notation; say $\nu^{\prime}, \nu^{\prime\prime}$. Secondly, I wonder: If we expand our considertions to full 3-generational PMNS-mixing, then the neutrino states appearing in the "mass vector" are exactly the actual physical mass eigenstates of today's neutrino experiments, aren't they? | |
| May 18, 2017 at 5:32 | comment | added | user12262 | Cosmas Zachos: "Since we know so little about the [neutrino mass states] $\nu_i \!$ s it would be perverse to pretend the charged leptons mix [...]" -- Right. In other words: Since we know to manipulate and analyze charged leptons, as well as relevant hadrons, it has been possible for us to experimentally prepare and analyze neutrino samples in terms of their weak states ($\nu_e, \nu_{\mu}, \nu_{\tau}$), rather than their mass states (which nevertheless have meanwhile been established experimentally). The "present convention" represents our historic bias of experimental accessibility. | |
