On the zero modes of the Faddev-Popov operator in the Landau gauge
R. R. Landim, L. C. Q. Vilar, O. S. Ventura +1
Following Henyey procedure, we construct examples of zero modes of the Faddev-Popov operator in the Landau gauge in Euclidean space in D dimensions, for both SU(2) and SU(3 groups.…
On Gravity localization under Lorentz Violation in warped scenario
Victor Santos, C. A. S. Almeida
Recently Rizzo studied the Lorentz Invariance Violation (LIV) in a brane scenario with one extra dimension where he found a non-zero mass for the four-dimensional graviton. This le…
Gauge field localization on the Bloch Brane
W. T. Cruz, Aristeu R. P. Lima, C. A. S. Almeida
We present new results on the localization of gauge fields in thick brane models. The four-dimensional observable universe is considered to be a topological defect which is generat…
Brane bounce-type configurations in a string-like scenario
L. J. S. Sousa, C. A. S. Silva, C. A. S. Almeida
Brane world six dimensional scenarios with string like metric has been proposed to alleviate the problem of field localization. However, these models have been suffering from some…
Quantum Kalb-Ramond Field in D-dimensional de Sitter Spacetimes
G. Alencar, I. Guedes, R. R. Landim +1
In this work we investigate the quantum theory of the Kalb-Ramond fields propagating in dimensional de Sitter spacetimes using the dynamic invariant method developed by Lewis a…
Gravity localization in a string-cigar braneworld
Jose Euclides G. Silva, Victor Santos, C. A. S. Almeida
We proposed a six dimensional string-like braneworld built from a warped product between a 3-brane and the Hamilton cigar soliton space, the string-cigar braneworld. This transvers…
