Description: Symmetry, Vol. 10, Pages 302: Fermion Scattering in a CPT-Even Lorentz Violation Quantum Electrodynamics Symmetry doi: 10.3390/sym10080302 Authors: Frederico Santos Manoel Ferreira In this work, we reassess two known processes of Quantum Electrodynamics involving electrons and muons. The photon propagator is modified by a CPT-even Lorentz-violating (LV) tensor, while fermion lines and the vertex interaction are not altered. Using the Feynman rules, the associated cross sections for unpolarized scatterings are evaluated, revealing the usual energy dependence and Lorentz-violating contributions that induce space anisotropy. A possible route to constraining the LV coefficients is presented and the results properly commented.
