Does a randall-sundrum scenario create the illusion of a torsion-free universe?

چکیده
We consider spacetime with torsion in a Randall-Sundrum scenario where torsion, identified with the rank-2 Kalb-Ramond field, exists in the bulk together with gravity. While the interactions of both graviton and torsion in the bulk are controlled by the Planck mass, an additional exponential suppression comes for the torsion zero-mode on the visible brane. This may serve as a natural explanation of why the effect of torsion is so much weaker than that of curvature on the brane. The massive torsion modes, on the other hand, are correlated with the corresponding gravitonic modes and may be detectable in TeV-scale experiments.

A Randall-Sundrum scenario with bulk dilaton and torsion
We consider a string-inspired torsion-dilaton-gravity action in a Randall-Sundrum brane world scenario and show that, in an effective four-dimensional theory on the visible brane, the rank-2 antisymmetric Kalb-Ramond field (source of torsion) is exponentially suppressed. The result is similar to our earlier result in [13], where no dilaton was present in the bulk. This offers an explanation of ...
متن کاملCosmological expansion in the Randall - Sundrum brane world scenario
The cosmology of the Randall-Sundrum scenario for a positive tension brane in a 5D universe with localized gravity has been studied previously. In the radiation-dominated universe, it was suggested that there are two solutions for the cosmic scale factor a(t): the standard solution a;t, and a solution a;t, which is incompatible with standard big bang nucleosynthesis. In this paper, we reconside...

The cosmology of the Randall-Sundrum scenario for a positive tension brane in a 5-D Universe with localized gravity has been studied previously. In the radiation-dominated Universe, it was suggested that there are two solutions for the cosmic scale factor a(t) : the standard solution a ∼ t1/2, and a solution a ∼ t1/4, which is incompatible with standard big bang nucleosynthesis.

متن کاملNested Braneworlds and Strong Brane Gravity Typeset Using Revt E X
We find the gravitational field of a ‘nested’ domain wall living entirely within a brane-universe, or, a localised vortex within a wall. For a vortex living on a critical Randall-Sundrum brane universe, we show that the induced gravitational field on the brane is identical to that of an (n−1)-dimensional vacuum domain wall. We also describe how to set-up a nested Randall-Sundrum scenario using ...
