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

TL;DR

This paper investigates how nonminimal Lorentz-violating couplings affect elastic light-by-light scattering in quantum electrodynamics, revealing new features in the scattering process due to Lorentz violation.

Contribution

It introduces and analyzes nonminimal Lorentz-violating couplings in QED, specifically their impact on photon-photon scattering at the one-loop level, highlighting novel characteristics.

Findings

One-loop elastic photon-photon scattering is affected by Lorentz violation.

New scattering features emerge due to nonminimal couplings.

The study provides insights into potential observable effects of Lorentz violation.

Abstract

In the last years the Lorentz Violation scheme was implemented in QFT, in special in standard model of particle physics, in an attempt to explain our actual open problems. In this work we analyze nonminimal couplings between a Lorentz-violating 4-vector and the photon field and the leptonic current of QED. The 1-loop contribution of the elastic photon-photon scattering is showed and the novel characteristics which arose are pointed out.
