Localization of Various Bulk Fields on a Brane
We report the issues of localization of various bulk fields on a brane in a curved background from a local field-theoretic viewpoint where a special attention is paid to a warp geometry in a general space-time dimension. We point out that spin 0 scalar field and spin 2 graviton are naturally localized on a brane with the exponentially decreasing warp factor, while spin 1/2 and 3/2 fermionic fie...
متن کاملGravitational Localization of All Local Fields on the Brane
We present a new (p − 1)-brane solution to Einstein’s equations in a general spacetime dimension. This solution is a natural generalization of the stringlike defect solution with codimension 2 in 6 space-time dimensions, which has been recently discovered by Gogberashvili and Singleton, to a general (p − 1)-brane solution with codimension n in general D = p+n space-time dimensions. It is shown ...
متن کاملLocalization of Kaluza-Klein gauge fields on a brane
In phenomenological models with extra dimensions there is a natural symmetry group associated to a brane universe, – the group of rotations of normal bundle of the brane. We consider Kaluza-Klein gauge fields corresponding to this group and show that they can be localized on the brane in models with warped extra dimensions. These gauge fields are coupled to matter fields which have nonzero rota...
متن کاملDynamical localization of gauge fields on a brane
We propose a dynamical mechanism of localization of gauge fields on a brane in which gauge bosons are excitations of the brane itself or composites made out of matter fields localized on the brane. The mechanism is operative for both Abelian and non-Abelian gauge fields. Several scalar and scalar-fermion composite models of gauge fields are considered. The models exhibit exact gauge invariance ...
متن کاملSmooth tensionful higher-codimensional brane worlds with bulk and brane form fields
Completely regular tensionful codimension-n brane world solutions are discussed, where the core of the brane is chosen to be a thin codimension-(n− 1) shell in an infinite volume flat bulk, and an Einstein-Hilbert term localized on the brane is included (Dvali-Gabadadze-Porrati models). In order to support such localized sources we enrich the vacuum structure of the brane by the inclusion of lo...
