On a possible relationship between lepton mixing and the stability of dark matter
I comment on the proposal that the stability of dark matter may be due to an unbroken 2 symmetry contained in the partially broken lepton flavour symmetry group.I remark that (1) there is no 2 symmetry apparent in the lepton mass spectrum and in lepton mixing, (2) predictive models of …
