We find all possible relations among physical observables arising from neutrino mass matrices that describe in a natural way the currently observed pattern (theta(23) and theta(12) large, Deltam(.)(2)/Deltam(Atm)(2) and theta(13) small) in terms of a minimum number of parameters. Natural here means due only to the relative smallness (vanishing) of some parameters in the relevant lagrangian, without special relations or accidental cancellations among them.

Abstract
We find all possible relations among physical observables arising from neutrino mass matrices that describe in a natural way the currently observed pattern (theta(23) and theta(12) large, Deltam(.)(2)/Deltam(Atm)(2) and theta(13) small) in terms of a minimum number of parameters. Natural here means due only to the relative smallness (vanishing) of some parameters in the relevant lagrangian, without special relations or accidental cancellations among them.| File | Dimensione | Formato | |
