Ultraviolet modified photons and anisotropies in the cosmic microwave background radiation
arXiv:hep-ph/0510113 · doi:10.1016/j.physletb.2006.02.014
Abstract
We discuss a minimal canonical modification of electrodynamics in order to account for ultraviolet Lorentz violating effects. This modification creates a birefringence that rotates the polarization planes from different directions. Such effects might be detectable in the anisotropic polarization of the Cosmic Microwave Background radiation.
