Neutrino mass and the Standard Model
F. R. Klinkhamer
It is pointed out (not for the first time) that the minimal Standard Model, without additional gauge-singlet right-handed neutrinos or isotriplet Higgs fields, allows for nonvanish…
Spontaneously broken Lorentz invariance from the dynamics of a heavy sterile neutrino
F. R. Klinkhamer
A relativistic theory for neutrino superluminality is presented (in principle, the same mechanism applies also to other fermions). The theory involves the standard-model particles…
Superluminal muon-neutrino velocity from a Fermi-point-splitting model of Lorentz violation
F. R. Klinkhamer
A particular Fermi-point-splitting (FPS) model is proposed, which allows, for finite values of the three-momentum, the group and phase velocities of the muon-flavor neutrino in vac…
Models for low-energy Lorentz violation in the photon sector: Addendum to 'Consistency of isotropic modified Maxwell theory'
F. R. Klinkhamer, M. Schreck
In a previous article [arXiv:1011.4258], we established the consistency of isotropic modified Maxwell theory for a finite range of the Lorentz-violating parameter \tilde{kappa}_{tr…
Superluminal neutrino, flavor, and relativity
F. R. Klinkhamer
Modified neutrino dispersion relations, which still obey the relativity principle, can have both a superluminal (muon-type) neutrino and a luminal (electron-type) neutrino, as long…
Superluminal neutrino and spontaneous breaking of Lorentz invariance
F. R. Klinkhamer, G. E. Volovik
Generally speaking, the existence of a superluminal neutrino can be attributed either to re-entrant Lorentz violation at ultralow energy from intrinsic Lorentz violation at ultrahi…
