Regimes of Yang--Mills theory in the presence of a constant vector background
D. R. Granado, A. J. G. Carvalho, A. Yu. Petrov +1
In this paper, we take into account the Gribov copies present in 3D Yang-MIlls-Higgs theory with a constant vector background whose presence breaks the Lorentz symmetry. The consta…
Non-Abelian aether-like term in four dimensions
A. J. G. Carvalho, D. R. Granado, J. R. Nascimento +1
The non-Abelian aether-like Lorentz-breaking term, involving triple and quartic self-coupling vertices, is generated from the non-Abelian generalization of the Lorentz-breaking ext…
Perturbative generation of photon Lorentz violating terms from a pseudo-tensor Lorentz-breaking extension of QED
A. J. G. Carvalho, A. F. Ferrari, A. M. de Lima +2
We consider an extended QED with the addition of a dimension-five Lorentz-breaking coupling between spinor and gauge fields, involving a pseudo-tensor . The specific form…
