Lorentz-violating electrodynamics and the cosmic microwave background
Alan Kostelecky, Matthew Mewes
Possible Lorentz-violating effects in the cosmic microwave background are studied. We provide a systematic classification of renormalizable and nonrenormalizable operators for Lore…

Spacetime-varying couplings and Lorentz violation
Alan Kostelecky, Ralf Lehnert, Malcolm Perry
Spacetime-varying coupling constants can be associated with violations of local Lorentz invariance and CPT symmetry. An analytical supergravity cosmology with time-varying fine-str…
