Analysis of cosmic microwave background radiation in the presence of Lorentz violation
arXiv:0710.1110
Abstract
We examine the effects Lorentz violation on observations of cosmic microwave background radiation. In particular, we focus on changes in polarization caused by vacuum birefringence. We place stringent constraints on previously untested violations.
