Abstract

The first higher derivative term of the photon sector of Lorentz-violating QED, with operator of mass dimension d=5d=5, is radiatively induced from the fermion sector, in which contains a derivative term with the dimensionless coefficient gλμνg^{\lambda\mu\nu}. The calculation is performed perturbatively in the coefficient for Lorentz violation, and due to the fact that the contributions are quadratically divergent, we adopt dimensional regularization.
