Lorentz Violation at One Loop

Abstract

The proof of one-loop renormalizability of the general Lorentz- and CPT-violating extension of quantum electrodynamics is described. Application of the renormalization-group method is discussed and implications for theory and experiment are considered.Comment: 10 pages, 28 figures, latex, uses sprocl.sty (included), talk presented at the Second Meeting on CPT and Lorentz Symmetry, Bloomington, IN, August 200
