  Lorentz violation has been a popular field in recent years in the search for
new physics beyond the Standard Model. We present a general method to build all
Lorentz-violating terms in gauge field theories, including ones involving
operators of arbitrary mass dimension. Applying these results to two types of
experiments in high-energy colliders, light-by-light scattering and
deep-inelastic scattering, we extract first bounds on certain coefficients for
Lorentz violation.
