S-matrix amplitudes for the electron-electron scattering are calculated in order to verify the quantum equivalence of dual models. We used an extended Quantum Electrodynamics with CPT-even Lorentz-violating kinetic and mass terms, which was used in a process of gauge embedding, known as Noether dualizationn method (NDM), in order to generate its gauge-invariant dual model. The physical equivalence was established at tree-level and the cross section was calculated to second order in the Lorentz-violating parameter.

  1. Nonrelativistic effective potential of the bumblebee model

    hep-th 2025-12 conditional novelty 5.0

    The leading-order nonrelativistic potential in the bumblebee model is a Coulomb potential with charge rescaled by (1 - (mβξ/2)^2), producing a hydrogen level shift of order m^3β^2ξ^2.
