Gravity and Large Extra Dimensions [PDF]

open access: yesAdvances in Astronomy, 2011
The idea that quantum gravity can be realized at the TeV scale is extremely attractive to theorists and experimentalists alike. This proposal leads to extra spacial dimensions large compared to the Planck scale.

LHC bounds on large extra dimensions [PDF]

open access: yes, 2011
We derive new dominant bounds on the coefficient of the effective operator generated by tree-level graviton exchange in large extra dimensions from pp → jj data at LHC: MT > 2.1 TeV (ATLAS after 3.1/pb of integrated luminosity), MT > 3.4 TeV (CMS after ...

Asymmetrical large extra dimensions [PDF]

open access: green, 2000
We study scenarios in which there is a hierarchy of two sets of large compactified extra dimensions. One particularly interesting case has a single millimeter size extra dimension and five TeV^{-1} size dimensions.

Linear collider signals of an invisible Higgs boson in theories of large extra dimensions [PDF]

open access: green, 2004
We discuss the possibility of detecting a Higgs boson in future collider experiments if large extra dimensions are realized in nature. In such a case, the Higgs boson can decay invisibly by oscillating into a graviscalar Kaluza-Klein (KK) tower.

Universal Torsion-Induced Interaction from Large Extra Dimensions [PDF]

open access: green, 2000
We consider the Kaluza-Klein (KK) scenario in which only gravity exists in the bulk. Without the assumption of symmetric connection, the presence of brane fermions induces torsion.

Elimination of the Blue Loops in the Evolution of Intermediate-mass Stars by the Neutrino Magnetic Moment and Large Extra Dimensions [PDF]

open access: yesAstrophysical Journal, 2020
For searching beyond Standard Model physics, stars are laboratories that complement terrestrial experiments. Massless neutrinos in the Standard Model of particle physics cannot have a magnetic moment, but massive neutrinos have a finite magnetic moment ...

Leptogenesis in theories with large extra dimensions [PDF]

open access: bronze, 1999
We study the scenario of baryogenesis through leptogenesis in higher-dimensional theories, in which the scale of quantum gravity is many orders of magnitude smaller than the usual Planck mass.

Neutrino masses and mixing in models with large extra dimensions and localized fermions [PDF]

open access: yes, 2020
Using a low-energy effective field theory approach, we study some properties of models with large extra dimensions, in which quarks and leptons have localized wave functions in the extra dimensions.

New Supernova Limit on Large Extra Dimensions: Bounds on Kaluza-Klein Graviton Production [PDF]

open access: green, 2001
If large extra dimensions exist in nature, supernova (SN) cores will emit large fluxes of Kaluza-Klein gravitons, producing a cosmic background of these particles with energies and masses up to about 100 MeV.

Thick brane in Rastall gravity

open access: yesJournal of High Energy Physics, 2022
In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either
