Impact of radiative corrections on sterile neutrino scenarios
A. Ibarra, I. Navarro
In sterile neutrino scenarios, radiative corrections induce mass splittings proportional to the top Yukawa coupling, in contrast to the three active neutrino case where the induced…
General RG Equations for Physical Neutrino Parameters and their Phenomenological Implications
J. A. Casas, J. R. Espinosa, A. Ibarra +1
The neutral leptonic sector of the Standard Model presumably consists of three neutrinos with non-zero Majorana masses with properties further determined by three mixing angles and…
Theoretical Constraints on the Vacuum Oscillation Solution to the Solar Neutrino Problem
J. A. Casas, J. R. Espinosa, A. Ibarra +1
The vacuum oscillation (VO) solution to the solar anomaly requires an extremely small neutrino mass splitting, Delta m^2_{sol}\leq 10^{-10} eV^2. We study under which circumstances…
Nearly degenerate neutrinos, Supersymmetry and radiative corrections
J. A. Casas, J. R. Espinosa, A. Ibarra +1
If neutrinos are to play a relevant cosmological role, they must be essentially degenerate with a mass matrix of the bimaximal mixing type. We study this scenario in the MSSM frame…
Naturalness of nearly degenerate neutrinos
J. A. Casas, J. R. Espinosa, A. Ibarra +1
If neutrinos are to play a relevant cosmological role, they must be essentially degenerate. We study whether radiative corrections can or cannot be responsible for the small mass s…
