Scalar and tensor gauge field localization on deformed thick branes
W. T. Cruz, M. O. Tahim, C. A. S. Almeida
We make an analysis about several aspects of localization of a scalar field and a Kalb-Ramond gauge field in a specific four dimensional AdS membrane embedded in a five dimensional…
Tensor gauge field localization in branes
M. O. Tahim, W. T. Cruz, C. A. S. Almeida
In this work we study localization of a Kalb-Ramond tensorial gauge field on a membrane described by real scalar fields. The membrane is embedded in an AdS-type five dimensional bu…
Generalized axion-photon couplings and dual descriptions on brane-worlds
M. O. Tahim, C. A. S. Almeida
In this work we obtain topological and dual theories on brane-worlds in several dimensions. Our brane is a solitonic-like hypersurface embedded in a space-time with a specific dime…
Topological gravity localization on a delta-function like Brane
M. O. Tahim, C. A. S. Almeida
Besides the String Theory context, the quantum General Relativity can be studied by the use of constrained topological field theories. In the celebrated Plebanski formalism, the co…
Topological Gravity, the Hierarchy Problem and Axion Physics
Carlos Alberto Santos Almeida, Makarius Oliveira Tahim
In the last years higher dimensional physics has won importance. Despite the Superstrings, higher dimensional effects, in measurable scales of energy (some TeV), became only possib…
Gauge hierarchy from a topological viewpoint?
M. O. Tahim, C. A. S. Almeida
In this work we explore an alternative to the central point of the Randall-Sundrum brane world scenario, namely, the particular nonfactorizable metric, in order to solve the hierar…
