Issues on Radiatively Induced Lorentz and CPT Violation in Quantum Electrodynamics
arXiv:hep-th/0106035 · doi:10.1063/1.1435492
Abstract
Various ambiguous results on radiatively induced Lorentz and CPT violation in quantum electrodynamics with a modified fermionic sector are reviewed and possible explanations for this ambiguity appearing in the literature are commentated. Furthermore, joint between stringent limit from astrophysical observation and theoretical prediction on Lorenz and CPT violation is discussed.
