Cosmological Constant of the (p+1)-Dimensional World, Embedded in the d-Dimensional Bulk Space

  • Davoud Kamani
Article

Abstract

In this manuscript we study the cosmological constant of a (p+1)-dimensional world, which lives in the higher dimensional bulk space. We assume the extra dimensions are compact on tori. We consider two cases: positive and negative bulk cosmological constant. It is pointed out that the tiny cosmological constant of our world can be obtained by the dynamics of a scalar field and adjusting the parameters of the model. The cosmological constant of the dual world also will be discussed. We obtain the Dirac quantization of these cosmological constants.
