Um estudo sobre mecanismos de ocultação de dimensões extras.

Abstract

The dimensionality of the Universe is a theme of great interest nowadays. The reason is the possibility of the existence of new extra dimensions beyond the usual three spatial dimensions. In the low - energy regime (below 1TeV, probably) the extra dimensions are hidden from our experience. In this paper we study the mechanisms which keep the extra dimensions hidden, investigating how they work when employed to the Klein-Gordon equation defined in a space-time of five dimensions. Here we study specially the Kaluza-Klein's mechanism and the braneworld mechanism.
