Lorentz and CPT Violating Chern-Simons Term in the Derivative Expansion of QED
J. -M. Chung, Phillial Oh
Abstract
We calculate by the method of dimensional regularization and derivative expansion the one-loop effective action for a Dirac fermion with a Lorentz-violating and CPT-odd kinetic term in the background of a gauge field. We show that this term induces a Chern-Simons modification to Maxwell theory. Some related issues are also discussed.
