Phenomenology of Brane-World Cosmological Models
نویسنده
چکیده
We present a brief review of brane-world models — models in which our observable Universe with its standard matter fields is assumed as localized on a domain wall (three-brane) in a higher dimensional surrounding (bulk) spacetime. Models of this type arise naturally in M-theory and have been intensively studied during the last years. We pay particular attention to the covariant projection approach, the Cardassian scenario, to induced gravity models, self-tuning models and the Ekpyrotic scenario. A brief discussion is given of their basic properties and their connection with conventional FRW cosmology. PACS numbers: 04.50.+h, 11.25.Mj, 98.80.Jk

Brane-world cosmological perturbations
Brane-world models provide a phenomenology that allows us to explore the cosmological consequences of some M theory ideas, and at the same time to use precision cosmology as a test of these ideas. In order to achieve this, we need to understand how brane-world gravity affects cosmological dynamics and perturbations. This introductory review describes the key features of cosmological perturbatio...
متن کاملSidestepping the Cosmological Constant with Football-Shaped Extra Dimensions
We present an exact solution for a factorizable brane-world spacetime with two extra dimensions and explicit brane sources. The compactification manifold has the topology of a two-sphere, and is stabilized by a bulk cosmological constant and magnetic flux. The geometry of the sphere is locally round except for conical singularities at the locations of two antipodal branes, deforming the sphere ...
متن کاملA ug 2 00 0 Brane World Phenomenology and the Z 2 Symmetry
The Friedmann equation for a positive tension brane world with and without the Z2 symmetry is derived and the possible effects of dropping the Z2 symmetry on the expansion of our Universe are discussed. The global solutions for the metric in the infinite extra dimension case are found; cosmological constraints are discussed. This is applied to various phenomenological aspects of brane worlds, i...
متن کاملCosmological Brane Perturbations a
At the end of the last millennium it was realized that the traditional Kaluza-Klein approach is not the only possibility of dimensional reduction. An alternative approach was developed, the brane-world scenario. In this scenario the standard matter fields are constrained to a lower dimensional hypersurface, or brane, which is embedded in a higher dimensional spacetime, or bulk. The gravitationa...
متن کاملBrane Waves
In brane-world cosmology gravitational waves can propagate in the higher dimensions (i.e., in the ‘bulk’). In some appropriate regimes the bulk gravitational waves may be approximated by plane waves. We systematically study five-dimensional gravitational waves that are algebraically special and of type N. In the most physically relevant case the projected non-local stress tensor on the brane is...
