Flexible extra dimensions [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
This paper discusses the origin of the small parameters with the aim of explaining the Hierarchy problem. The flexible extra dimensions are an essential tool in the process by which physical parameters are formed.

Constraining extra dimensions using observations of black hole quasi-normal modes. [PDF]

open access: yesEur Phys J C Part Fields, 2022
The presence of extra dimensions generically modify the spacetime geometry of a rotating black hole, by adding an additional hair, besides the mass M and the angular momentum J, known as the ‘tidal charge’ parameter, β\documentclass[12pt]{minimal ...

Growing extra dimensions in AdS/CFT [PDF]

open access: yesJournal of High Energy Physics, 2019
What is the dimension of spacetime? We address this question in the context of the AdS/CFT Correspondence. We give a prescription for computing the number of large bulk dimensions, D, from strongly-coupled CFT d data, where “large” means parametrically ...

Extra kinetic dimensions for label discrimination

open access: yesNature Communications, 2022
Label discrimination is challenging in fluorescence microscopy due to broad spectra and narrow lifetime distribution. Here, the authors introduce extra kinetic dimensions by illuminating reversibly photoswitchable fluorophores with different intensities,

Dark energy, extra dimensions, and the Swampland [PDF]

open access: yesJournal of High Energy Physics, 2020
Perhaps the greatest challenge for fundamental theories based on compactification from extra dimensions is accommodating a period of accelerated cosmological expansion.

Search for dark matter, extra dimensions, and unparticles in monojet events in proton-proton collisions at [Formula: see text][Formula: see text]. [PDF]

open access: yesEur Phys J C Part Fields, 2015
Results are presented from a search for particle dark matter (DM), extra dimensions, and unparticles using events containing a jet and an imbalance in transverse momentum. The data were collected by the CMS detector in proton–proton collisions at the LHC

Non-invertible flavor symmetries in magnetized extra dimensions [PDF]

open access: yesJournal of High Energy Physics
We discuss non-invertible symmetries in toroidal compactifications of higher dimensional Yang-Mills theory with magnetic fluxes, which can be regarded as an effective action of type IIB string theory with magnetized D-branes.

Exploring extra dimensions through inflationary tensor modes [PDF]

open access: yesJournal of High Energy Physics, 2018
Predictions of inflationary schemes can be influenced by the presence of extra dimensions. This could be of particular relevance for the spectrum of gravitational waves in models where the extra dimensions provide a brane-world solution to the hierarchy ...

Large extra dimensions from higher-dimensional inflation [PDF]

open access: yesPhysical Review D, 2023
We propose the possibility that compact extra dimensions can obtain large size by higher dimensional inflation, relating the weakness of the actual gravitational force to the size of the observable universe.

Large extra dimensions and neutrino experiments [PDF]

open access: yesPhysical Review D, 2022
The existence of Large Extra Dimensions can be probed in various neutrino experiments. We analyze several neutrino data sets in a model with a dominant large extra dimension.
