Large Extra Dimensions from a Small Extra Dimension [PDF]

open access: yes, 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

Constraints on large extra dimensions from the MINOS experiment [PDF]

open access: yes, 2016
We report new constraints on the size of large extra dimensions from data collected by the MINOS experiment between 2005 and 2012. Our analysis employs a model in which sterile neutrinos arise as Kaluza-Klein states in large extra dimensions and thus ...

Localization of spinor fields in higher-dimensional braneworlds

open access: yesJournal of High Energy Physics, 2023
In this paper we investigate the localization of spinor fields in braneworld models by reducing a Dirac spinor in 2n + 2-dimensional spacetime to spinors in 2n dimensions.

Search for dark matter candidates and large extra dimensions in events with a jet and missing transverse momentum with the ATLAS detector [PDF]

open access: yesJournal of High Energy Physics, 2012
A search for new phenomena in events with a high-energy jet and large missing transverse momentum is performed using data from proton-proton collisions at \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts ...

Homogeneity, Flatness and "Large" Extra Dimensions [PDF]

open access: yes, 2001
We consider a model in which the universe is the direct product of a (3+1)-dimensional Friedmann, Robertson-Walker (FRW) space and a compact hyperbolic manifold (CHM). Standard Model fields are confined to a point in the CHM (i.e. to a brane).

Proof of dispersion relations for the amplitude in theories with a compactified space dimension

open access: yesJournal of High Energy Physics, 2020
The analyticity properties of the scattering amplitude in the nonforward direction are investigated for a field theory in the manifold R 3,1 ⨂ S 1.

Cosmic Rays and Large Extra Dimensions [PDF]

open access: yes, 2001
We have proposed that the cosmic ray spectrum "knee", the steepening of the cosmic ray spectrum at energy $E \gsim 10^{15.5}$ eV, is due to "new physics", namely new interactions at TeV cm energies which produce particles undetected by the experimental ...

Probing large extra dimensions with IceCube [PDF]

open access: yes, 2014
In models with Large Extra Dimensions the smallness of neutrino masses can be naturally explained by introducing gauge singlet fermions which propagate in the bulk.

Probing the anomalous γγγZ coupling at the LHC with proton tagging

open access: yesJournal of High Energy Physics, 2017
The sensitivities to the anomalous quartic gauge boson coupling γγγZ are estimated via γZ production with intact protons in the forward region at the LHC.

Cosmic ray boosted sub-GeV gravitationally interacting dark matter in direct detection

open access: yesJournal of High Energy Physics, 2020
Detections of non-gravitational interactions of massive dark matter (DM) with visible sector so far have given null results. The DM may communicate with the ordinary matter only through gravitational interaction.
