Flexible extra dimensions

European Physical Journal C: Particles and Fields, 2023
This paper discusses the origin of the small parameters with the aim of explaining the Hierarchy problem. The flexible extra dimensions are an essential tool in the process by which physical parameters are formed.

Inflation from Extra Dimensions [PDF]

AIP Conference Proceedings, 1999
The radial mode of n extra compact dimensions (the radion, b) can cause inflation in theories where the fundamental gravity scale, M, is smaller than the Planck scale M_P.

Disordered Extra Dimensions

New Journal of Physics, 2010
A very large extra dimension may contain many localized branes. We discuss the possibility to formulate such models as a spin system where each spin indicates the supersymmetry direction preserved by the corresponding brane.

Large Extra Dimensions from a Small Extra Dimension [PDF]

Journal of High Energy Physics, 2001
Models with extra dimensions have changed our understanding of the hierarchy problem. In general, these models explain the weakness of gravity by diluting gravity in a large bulk volume, or by localizing the graviton away from the standard model. In this

Inflation from Extra Dimensions [PDF]

Physics Letters B, 1994
A gravity-driven inflation is shown to arise from a simple higher dimensional universe. In vacuum, the shear of $n>1$ contracting dimensions is able to inflate the remaining three spatial dimensions.

Discerning Noncommutative Extra Dimensions [PDF]

Physical Review D, 2002
Experimental limits on the violation of four-dimensional Lorentz invariance imply that noncommutativity among ordinary spacetime dimensions must be small. Noncommutativity among extra, compactified spatial dimensions, however, is far less constrained and

Anisotropic Extra Dimensions [PDF]

Physical Review D, 2011
We consider the scenario where in a five-dimensional theory, the extra spatial dimension has different scaling than the other four dimensions. We find background maximally symmetric solutions, when the bulk is filled with a cosmological constant and at ...

The Absorptive Extra Dimensions [PDF]

Physical Review D, 2003
It is well known that gravity and neutrino oscillation can be used to probe large extra dimensions in a braneworld scenario. We argue that neutrino oscillation remains a useful probe even when the extra dimensions are small, because the brane-bulk ...

Extra Dimensions in Superstring Theory [PDF]

Nuclear Physics B, 1997
It was earlier shown that an SO(9,1) $\theta^\a$ spinor variable can be constructed from RNS matter and ghost fields. $\theta^\a$ has a bosonic worldsheet super-partner $\lambda^\a$ which plays the role of a twistor variable, satisfying $\lambda\Gamma ...

CP Violation and Extra Dimensions [PDF]

The European Physical Journal C, 2001
It is shown that the new sources of CP violation can be generated in the models with more than one extra dimensions. In the supersymmetric models on the space-time $M^4\times T^2/Z_2$, where the radius moduli have auxiliary vacuum expectation values and ...
