Hidden Photons in Extra Dimensions [PDF]

open access: yes, 2013
Additional U(1) gauge symmetries and corresponding vector bosons, called hidden photons, interacting with the regular photon via kinetic mixing are well motivated in extensions of the Standard Model. Such extensions often exhibit extra spatial dimensions.

On extra forces from large extra dimensions

open access: yes, 2007
The motion of a classical test particle moving on a 4-dimensional brane embedded in an $n$-dimensional bulk is studied in which the brane is allowed to fluctuate along the extra dimensions.

CDMS, Supersymmetry and Extra Dimensions [PDF]

open access: yes, 2006
The CDMS experiment aims to directly detect massive, cold dark matter particles originating from the Milky Way halo. Charge and lattice excitations are detected after a particle scatters in a Ge or Si crystal kept at ~30 mK, allowing to separate nuclear ...

Wormholes leading to extra dimensions [PDF]

open access: yesGravitation & Cosmology, 2016
In 6D general relativity with a scalar field as a source of gravity, a new type of static wormhole solutions is presented: such wormholes connect our universe with a small 2D extra subspace with a universe where this extra subspace is large, and the ...

GIMPs from extra dimensions

open access: yesPhysics Letters B, 2010
We study a scalar field theory in a flat five-dimensional setup, where a scalar field lives in a bulk with a Dirichlet boundary condition, and give an implementation of this setup to the Froggatt- Nielsen (FN) mechanism. It is shown that all couplings of physical field of the scalar with the all brane localized standard model particles are vanishing ...

Large and infinite extra dimensions [PDF]

open access: yes, 2001
The emphasis in the developmet of theories with more than three spatial dimensions has recently shifted towards ``brane world'' picture, which assumes that ordinary matter (with possible exceptions of gravitons and other, hypothetic, particles which ...

Stable skyrmions from extra dimensions [PDF]

open access: yes, 2007
We show that skyrmions arising from compact five dimensional models have stable sizes. We numerically obtain the skyrmion configurations and calculate their size and energy. Although their size strongly depends on the magnitude of localized kinetic-terms,

Constraining extra-spatial dimensions with observations of GW170817 [PDF]

open access: yesClassical and quantum gravity, 2019
We derive the modifications introduced by extra-spatial dimensions beyond the four dimensional spacetime on the macroscopic properties of neutron stars, which in turn affect the gravitational wave spectrum of their binaries.

Phenomenology of Extra Dimensions [PDF]

open access: yesStrings, Branes and Extra Dimensions, 2004
If the structure of spacetime is different than that readily observed, gravitational physics, particle physics and cosmology are all immediately affected. The physics of extra dimensions offers new insights and solutions to fundamental questions arising in these fields. Novel ideas and frameworks are continuously born and evolved.

Inflation from periodic extra dimensions [PDF]

open access: yes, 2016
We discuss a realization of a small field inflation based on string inspired supergravities. In theories accompanying extra dimensions, compactification of them with small radii is required for realistic situations.
