Lorentz-invariant CPT violation [PDF]
A Lorentz-invariant CPT violation, which may be termed as long-distance CPT violation in contrast to the familiar short-distance CPT violation, has been recently proposed. This scheme is based on a non-local interaction vertex and characterized by an infrared divergent form factor.

On the lightlike Lorentz violation
We consider the lightlike spontaneous Lorentz invariance violation (SLIV) appearing through the zero “length-fixing” constraint put on a gauge vector field, AμAμ=0, and discuss its physical consequences in the framework of a conventional QED and beyond ...

The phenomena of neutrino oscillations offer a great potential for probing new-physics beyond the Standard Model. Any additional effects on neutrino oscillations can help understand the nature of the non-standard effects.

Constraining Lorentz invariance violation with next-generation long-baseline experiments
Unified theories such as string theory and loop quantum gravity allow the Lorentz Invariance Violation (LIV) at the Planck Scale (M P ~ 1019 GeV). Using an effective field theory, this effect can be observed at low energies in terms of new interactions ...

Neutrino telescope modelling of Lorentz invariance violation in oscillations of atmospheric neutrinos [PDF]
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.

Searching Lorentz invariance violation from cosmic photon attenuation
Lorentz invariance violation (LIV) can change the threshold behavior predicted by special relativity and cause threshold anomalies which affect the propagation of cosmic photons.

Crossing of the Phantom Divided Barrier with Lorentz Invariance Violating Fields [PDF]
We study possible crossing of the phantom divided barrier in a Lorentz invariance violating dark energy model. Lorentz invariance violation which is achieved by introducing a vector field in the action, incorporates directly in the dynamics of the scalar

Lorentz invariance violation and generalized uncertainty principle [PDF]
There are several theoretical indications that the quantum gravity approaches may have predictions for a minimal measurable length, and a maximal observable momentum and throughout a generalization for Heisenberg uncertainty principle. The generalized uncertainty principle (GUP) is based on a momentum-dependent modification in the standard dispersion ...
