Chern-Simons Violation of Lorentz and PCT Symmetries in Electrodynamics
R. Jackiw
TL;DR
This paper reviews recent Lorentz and PCT symmetry-violating modifications of electromagnetism, discusses their experimental implications, and concludes that current data strongly disfavor their existence in nature.
Contribution
It provides a comprehensive review of proposed Lorentz-PCT violating electromagnetism models and assesses their viability based on experimental evidence.
Findings
Experimental data rules out Lorentz-PCT violation in electromagnetism
Reviewed recent theoretical modifications of electromagnetism
Concluded such modifications are incompatible with observations
Abstract
Recently proposed Lorentz-PCT noninvariant modifications of electromagnetism are reviewed. Their experimental consequences are described, and it is argued that available data decisively rules out their occurrence in Nature.
