Electrophobic Lorentz Invariance Violation for Neutrinos and the See-saw Mechanism
نویسنده
چکیده
In this talk we show how Lorentz invariance violation (LIV) can occur for Majorana neutrinos, without inducing LIV in the charged leptons via radiative corrections. Such “electrophobic” LIV is due to the Majorana nature of the LIV operator together with electric charge conservation. Being free from the strong constraints coming from the charged lepton sector, electrophobic LIV can in principle be as large as current neutrino experiments permit. On the other hand electrophobic LIV could be naturally small if it originates from LIV in some singlet “right-handed neutrino” sector, and is felt in the physical left-handed neutrinos via a see-saw mechanism.

متن کاملLorentz Violation and Neutrinos *
Neutrino oscillations provide an opportunity for sensitive tests of Lorentz invariance. This talk reviews some aspects of Lorentz violation in neutrinos and the prospect of testing Lorentz invariance in neutrinooscillation experiments. A general Lorentz-violating theory for neutrinos is discussed, and some signals of Lorentz violation are identified.
متن کاملNeutrino Telescope Modelling of Lorentz Invariance Violation in Oscillations of Atmospheric Neutrinos
One possible feature of quantum gravity may be the violation of Lorentz invariance. In this paper we consider one particular manifestation of the violation of Lorentz invariance, namely modified dispersion relations for massive neutrinos. We show how such modified dispersion relations may affect atmospheric neutrino oscillations. We then consider how neutrino telescopes, such as ANTARES, may be...

متن کاملMirror Neutrinos and the Early Universe
The Exact Parity Model (EPM) sees the ordinary particle sector reflected, darkly, in a mirror sector. It is a phenomenologically acceptable extension of the Standard Model (SM) of particle physics which displays invariance under Improper Lorentz Transformations (Parity and Time-Reversal invariance). Remarkably, the invariance or otherwise of microphysical laws and the physical vacuum under the ...
