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.

No-go theorems on localization of gravity around higher codimensional branes in noncompact extra dimensions

open access: yesJournal of High Energy Physics, 2021
We study the brane world scenario of a single brane (or a single stack of branes) with codimension higher than one. When the extra dimensions are not small, localization of gravity around the brane is needed in order to reproduce the observable four ...

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

Dark bubbles and black holes

open access: yesJournal of High Energy Physics, 2021
In this paper we study shells of matter and black holes on the expanding bubbles realizing de Sitter space, that were proposed in [4]. We construct explicit solutions for a rigid shell of matter as well as black hole like solutions.

Emergent de Sitter cosmology near black hole horizon

open access: yesJournal of High Energy Physics, 2022
We propose an effective model for an exponentially expanding universe in the brane-world scenario. The setup consists of a 5D black hole and a brane close to the black hole horizon.

Leptophilic U(1) massive vector bosons from large extra dimensions

open access: yesPhysics Letters B, 2021
We demonstrate that the discrepancy between the anomalous magnetic moment measured at BNL and Fermilab and the Standard Model prediction could be explained within the context of low-scale gravity and large extra-dimensions.

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.

Gravity-mediated dark matter annihilation in the Randall-Sundrum model

open access: yesJournal of High Energy Physics, 2017
Observational evidence for dark matter stems from its gravitational interactions, and as of yet there has been no evidence for dark matter interacting via other means. We examine models where dark matter interactions are purely gravitational in a Randall-

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.

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.
