Do anomalies break the momentum routing invariance?
A. R. Vieira
The diagrammatic computation of anomalies is usually associated with the breaking of the momentum routing invariance. This is because the momentum routing is usually chosen to fulf…
Spinor Adjoints, Gauge Invariance and a new Road to Sterile Neutrinos
R. J. Bueno Rogerio, G. B. de Gracia
In this work, we analyze the possibilities of certain gauge transformations regarding some specific spinorial dual structures. To this end, we define a general structure, which can…
Unraveling the Physical Meaning Behind Elko's Dual structure
Gabriel Brandão de Gracia, Rodolfo José Bueno Rogerio, Luca Fabbri
In this work, we shall analyze the necessity of a proper definition of the dual structure for Elko spinors, and singular spinors in general. We examine in detail why the Dirac dual…
Scale anomaly in a Lorentz and CPT-violating Quantum Electrodynamics
J. S. Porto, A. R. Vieira
We compute the classical and the quantum breaking of the dilatation current in the minimal Lorentz and CPT-violating quantum electrodynamics. At the classical level, scale symmetry…
The full Lorentz-violating vacuum polarization tensor: low and high energy limits
J. C. C. Felipe, A. Yu. Petrov, A. P. Baêta Scarpelli +1
We compute the full vacuum polarization tensor in the fermion sector of Lorentz-violating QED. Even if we assume momentum routing invariance of the Feynman diagrams, it is not poss…
The unambiguous Lorentz-violating induced terms
A. R. Vieira
In this work, we show that surface terms, which map dependence on regularization, can be fixed requiring momentum routing invariance of tadpoles or diagrams with more external legs…
