Description
We review the $Sim(2)$ invariant infrared regularization of Very Special Relativity models that we have proposed recently and apply it to compute loop corrections in quantum electrodynamics with VSR masses for neutrino and photon. We computed the anomalous magnetic moment of the electron and using the most recent data for the photon mass, we obtain a bound for the electron
neutrino mass.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.
