Testing CPT invariance by using C-even neutral-meson--antimeson correlated states
G. V. Dass, W. Grimus, L. Lavoura
We consider the decays of a correlated neutral-meson--antimeson state with C-parity +1. We show that there is CPT noninvariance in the mixing of the neutral mesons if, for any two…
Seesaw model with softly broken L_e - L_μ- L_τ
L. Lavoura, W. Grimus
We enlarge the lepton sector of the Standard Model by adding to it two right-handed neutrino singlets, and propose a model based on the seesaw mechanism and on the lepton number $\…
The seesaw mechanism at arbitrary order: disentangling the small scale from the large scale
W. Grimus, L. Lavoura
We develop a recipe which allows one to recursively and uniquely decouple the large scale from the small scale in mass matrices of the seesaw type, up to any order in the inverse o…
A neutrino mass matrix with seesaw mechanism and two-loop mass splitting
W. Grimus, L. Lavoura
We propose a model which uses the seesaw mechanism and the lepton number to achieve the neutrino mass spectrum and , together with a…
New model for the neutrino mass matrix
L. Lavoura
I suggest a model based on a softly broken symmetry L_e - L_mu - L_tau and on Babu's mechanism for two-loops radiative generation of the neutrino masses. The model predicts that on…
