Equivalence between the Lovelock-Cartan action and a constrained gauge theory
O. C. Junqueira, A. D. Pereira, G. Sadovski +3
We show that the four-dimensional Lovelock-Cartan action can be derived from a massless gauge theory for the group with an additional BRST trivial part. The model is orig…
Lorentz-violating Yang-Mills theory: discussing the Chern-Simons-like term generation
Tiago R. S. Santos, Rodrigo F. Sobreiro
We analyze the Chern-Simons-like term generation in the CPT-odd Lorentz-violating Yang-Mills theory interacting with fermions. Moreover, we study the anomalies of this model as wel…
Gauge anomalies in Lorentz-violating QED
Tiago R. S. Santos, Rodrigo F. Sobreiro
In this work we study the issue of gauge anomalies in Lorentz-violating QED. To do so, we opt to use the Becchi-Rouet-Stora-Tyutin formalism within the algebraic renormalization ap…
Gauge field spectrum in massive Yang-Mills theory with Lorentz violation
T. R. S. Santos, R. F. Sobreiro, A. A. Tomaz
The spectrum of the massive CPT-odd Yang-Mills propagator with Lorentz violation is performed at tree-level. The modification is due to mass terms generated by the exigence of mult…
Remarks on the renormalization properties of Lorentz and CPT violating quantum electrodynamics
Tiago R. S. Santos, Rodrigo F. Sobreiro
In this work, we employ algebraic renormalization technique to show the renormalizability to all orders in perturbation theory of the Lorentz and CPT violating QED. Essentially, we…
Renormalizability of Yang-Mills theory with Lorentz violation and gluon mass generation
T. R. S. Santos, R. F. Sobreiro
We show that pure Yang-Mills theories with Lorentz violation are renormalizable to all orders in perturbation theory. To do this, we employ the algebraic renormalization technique.…
From Yang-Mills theory to induced gravity
T. S. Assimos, A. D. Pereira, T. R. S. Santos +3
From pure Yang-Mills action for the group in four Euclidean dimensions we obtain a gravity theory in the first order formalism. Besides the Einstein-Hilbert term…
Formal aspects of spin currents in material media
T. R. S. Santos, R. F. Sobreiro, V. J. Vasquez Otoya
The relativistic generalization of the broken continuity equation that describes spin currents is exploited in general material media. The field theoretical techniques for the usua…
