Identification of new nonrenormalizable operators affecting photon behavior
Guidance for future experimental tests of Lorentz invariance
Abstract
The Standard-Model Extension (SME) provides a theoretical framework for tests of Lorentz invariance. To date, most studies have focused on the minimal SME, which restricts attention to operators of renormalizable dimension. Here, we review recent studies involving the nonrenormalizable photon sector of the SME.
