Elastic light-by-light scattering in a nonminimal Lorentz violation scenario

Over the past years, a Lorentz symmetry violation scheme has been implemented in the Standard Model of particle physics in an attempt to explain important open problems. In connection with this work, we determine the effect of two Lorentz-violating nonminimal couplings on the differential cross section for elastic photon-photon scattering, both in the high- and low-energy regimes. Novel characteristics are pointed out: in particular, a periodic...
