摘要

我们考虑了非常狭义相对论（VSR）量子电动力学（QED）中光子质量不为零的光散射。为了保持量规不变性和 Sim(2) 对称性，我们使用了最近引入的 VSR 理论红外正则化。此外，我们还证明了所有具有任意数量光子外腿和零费米子外腿的一环图都会按照统一性的要求，还原为具有有效电子质量的标准 QED 结果。由此可见，欧拉-海森堡拉格朗日与 QED 中的拉格朗日相同。光对光散射的总截面呈现出微小的各向异性，可以在宇宙学尺度上探测到。特别是在低光子频率的宇宙微波背景（CMB）辐射中。

Light-light scattering in Very Special Relativity Quantum Electrodynamics and cosmic anisotropies

We consider scattering of light by light in Very Special Relativity (VSR) Quantum Electrodynamics (QED) with a non-zero photon mass. In order to preserve gauge invariance and Sim(2) symmetry we made use of a recently introduced infrared regularization of VSR theories. Additionally, we show that all one loop diagrams with any number of photon external legs and zero fermion legs reduce to the standard QED result with the effective electron mass, as required by unitarity. It follows that the Euler-Heisenberg Lagrangian is the same as in QED. The total cross section of scattering of light by light exhibits tiny anisotropies that could be detected at cosmological scales. In particular, they should be looked at the Cosmic Microwave Background (CMB) Radiation for low photon frequencies.
