THE MINIMAL LENGTH AND LARGE EXTRA DIMENSIONS [PDF]

open access: yesModern Physics Letters A, 2004
Planck scale physics represents a future challenge, located between particle physics and general relativity. The Planck scale marks a threshold beyond which the old description of spacetime breaks down and conceptually new phenomena must appear. Little is known about the fundamental theory valid at Planckian energies, except that it necessarily seems ...

Large extra dimensions and cosmological problems [PDF]

open access: yesPhysical Review D, 2001
We consider a variant of the brane-world model in which the universe is the direct product of a Friedmann, Robertson-Walker (FRW) space and a compact hyperbolic manifold of dimension $d\geq2$. Cosmology in this space is particularly interesting. The dynamical evolution of the space-time leads to the injection of a large entropy into the observable (FRW)

Search for new phenomena in high-mass diphoton final states using 37 fb−1 of proton–proton collisions collected at s=13 TeV with the ATLAS detector

open access: yesPhysics Letters B, 2017
Searches for new phenomena in high-mass diphoton final states with the ATLAS experiment at the LHC are presented. The analysis is based on pp collision data corresponding to an integrated luminosity of 36.7 fb−1 at a centre-of-mass energy s=13 TeV ...

NOMA-Based Random Access in mMTC XL-MIMO

open access: yesIEEE Access, 2023
In machine-type communication (MTC), massive access attempts are generated and the massive MIMO is the key technology to support this demand. To support massive MTC (mMTC), the recent extra-large scale massive multiple-input multiple-output (XL-MIMO ...

Entanglement transfer from quantum matter to classical geometry in an emergent holographic dual description of a scalar field theory

open access: yesJournal of High Energy Physics, 2021
Applying recursive renormalization group transformations to a scalar field theory, we obtain an effective quantum gravity theory with an emergent extra dimension, described by a dual holographic Einstein-Klein-Gordon type action.

A small weak scale from a small cosmological constant

open access: yesJournal of High Energy Physics, 2017
We propose a framework in which Weinberg’s anthropic explanation of the cosmological constant problem also solves the hierarchy problem. The weak scale is selected by chiral dynamics that controls the stabilization of an extra dimension.

LARGE EXTRA DIMENSIONS AT LINEAR COLLIDERS [PDF]

open access: yesInternational Journal of Modern Physics A, 2000
In this talk, I first present the motivation for theories wherein the extra spacetime dimensions can be compactified to have large magnitudes. In particular, I discuss the Arkani-Hamed, Dimopoulos, Dvali (ADD) scenario. I present the constraints that have been derived on these models from current experiments and the expectations from future colliders.

Smooth braneworld in 6-dimensional asymptotically AdS spacetime

open access: yesJournal of High Energy Physics, 2021
In this paper, we investigate a six-dimensional smooth thick braneworld model which contains a compact extra dimension and an infinite large one. The braneworld is generated by a real scalar field with a ϕ 6 potential and the bulk is an asymptotically ...
