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, 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…

Dualization of non-Abelian model
C. A. S. Almeida, R. R. Landim, D. M. Medeiros
In this work we show a dualization process of a non-Abelian model with an antisymmetric tensor gauge field in a three-dimensional space-time. We have constructed a non-Abelian gaug…
