Axion-Photon Interaction from Nonminimal Dimension-5 Lorentz-Violating Operators
A. J. G. Carvalho, A. G. Dias, A. F. Ferrari +3
In this paper, we discuss various possible schemes for the perturbative generation of the axion-photon interaction term in different Lorentz-breaking extensions of QED, involving o…
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…
Next-to-leading-order predictions for single vector-like quark production at the LHC
Giacomo Cacciapaglia, Alexandra Carvalho, Aldo Deandrea +5
We propose simulation strategies for single production of third generation vector-like quarks at the LHC, implementing next-to-leading-order corrections in QCD and studying in deta…
Single production of vector-like quarks with large width at the Large Hadron Collider
Alexandra Carvalho, Stefano Moretti, Dermot O'Brien +2
Vector-Like Quarks (VLQs) are predicted by several theoretical scenarios of new physics and, having colour quantum numbers, can copiously be produced at the Large Hadron Collider (…
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…
