Three- and Four-Point Functions in CPT-Even Lorentz-Violating Scalar QED
B. Altschul, L. C. T. Brito, J. C. C. Felipe +3
The renormalization of quantum field theories usually assumes Lorentz and gauge symmetries, besides the general restrictions imposed by unitarity and causality. However, the set of…
