Searching for a dark dimension right-handed neutrino in KATRIN
Journal of High Energy PhysicsWe study the possibility that the Right-handed neutrino is a five-dimensional state propagating along a micron size extra dimension, as required in the dark dimension proposal.

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 may have discernable collider signatures.

Analysis of inflationary models in higher-dimensional uniform inflation
Journal of High Energy PhysicsWe consider higher-dimensional uniform inflation, in which the extra dimensions expand at the same rate as three-dimensional non-compact space during inflation.

Flavour physics and extra-dimensions
EPJ Web of Conferences, 2018 Randall-Sundrum (RS) model of warped extra-dimensions were originally proposed to explain the Planck-weak scale hierarchy. It was soon realised that modifications of the original setup, by introducing the fields in the bulk, has several interesting ...

Warped universal extra dimensions [PDF]
Journal of High Energy Physics, 2011 We consider a 5D warped scenario with a KK-parity symmetry, where the non-trivial warping arises from the dynamics that stabilizes the size of the extra dimension. Generically, the lightest Kaluza-Klein (KK) particle is the first excitation of the radion field, while the next-to-lightest Kaluza-Klein particle is either the first excitation of the (RH ...

Dark dimension right-handed neutrinos confronted with long-baseline oscillation experiments
Journal of High Energy PhysicsRight-handed neutrinos are naturally induced by dark extra dimension models and play an essential role in neutrino oscillations. The model parameters can be examined by the long-baseline neutrino oscillation experiments.

Physics with large extra dimensions [PDF]
Nuclear Physics B - Proceedings Supplements, 2003 The recent understanding of string theory opens the possibility that the string scale can be as low as a few TeV. The apparent weakness of gravitational interactions can then be accounted by the existence of large internal dimensions, in the sub-millimeter region.

Exponentially large extra dimensions [PDF]
Physical Review D, 2002 We show how the presence of a very light scalar with a cubic self-interaction in six dimensions can stabilize the extra dimensions at radii which are naturally exponentially large, $r \sim \ell \exp [(4π)^3/g^2]$, where $\ell$ is a microscopic physics scale and $g$ is the (dimensionless) cubic coupling constant.
