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…
New results for deformed defects
C. A. Almeida, D. Bazeia, L. Losano +1
We extend a deformation prescription recently introduced and present some new soluble nonlinear problems for kinks and lumps. In particular, we show how to generate models which pr…
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…
