Graviton resonances on two-field thick branes
W. T. Cruz, L. J. S. Sousa, R. V. Maluf +1
This work presents new results about the graviton massive spectrum in two-field thick branes. Analyzing the massive spectra with a relative probability method we have firstly showe…
Matter-gravity scattering in the presence of spontaneous Lorentz violation
R. V. Maluf, Victor Santos, W. T. Cruz +1
Considering quantum gravity within the framework of effective field theory, we investigated the consequences of spontaneous Lorentz violation for the gravitational potential. In pa…
Kalb-Ramond field localization on the Bloch brane
W. T. Cruz, R. V. Maluf, C. A. S. Almeida
This work deals with new results on the Kalb-Ramond (KR) field localization in braneworld models. We consider a five-dimensional warped spacetime with an embedded 4D thick brane wh…
Radiative generation of the CPT-even gauge term of the SME from a dimension-five nonminimal coupling term
R. Casana, M. M. Ferreira, R. V. Maluf +1
In this letter we show for the first time that the usual CPT-even gauge term of the standard model extension (SME) can be radiatively generated, in a gauge invariant level, in the…
