On the ambiguities in the effective action in Lorentz-violating gravity
M. Gomes, T. Mariz, J. R. Nascimento +3
We investigate the occurrence of ambiguities for Lorentz-violating gravitational Chern-Simons term. It turns out that this term is accompanied by a coefficient depending on an unde…
The ambiguity-free four-dimensional Lorentz-breaking Chern-Simons action
F. A. Brito, J. R. Nascimento, E. Passos +1
The four dimensional Lorentz-breaking finite and determined Chern-Simons like action is generated as a one loop perturbative correction via an appropriate Lorentz-breaking coupling…
On the induction of the four-dimensional Lorentz-breaking non-Abelian Chern-Simons action
M. Gomes, J. R. Nascimento, E. Passos +2
A four-dimensional Lorentz-breaking non-Abelian Chern-Simons like action is generated as a one-loop perturbative correction via an appropriate Lorentz-breaking coupling of the non-…
