Classification of Robinson-Trautman and Kundt geometries with Large D limit

Journal of High Energy Physics, 2022
Algebraic classification of higher dimensional, shear-free, twist-free, expanding (or non-expanding) spacetime is studied with the limit of D → ∞. Similar to classification of any arbitrary dimension D > 4, this spacetime is Type I(b) or more special ...

A short travel for neutrinos in Large Extra Dimensions

Journal of High Energy Physics, 2018
Neutrino oscillations successfully explain the flavor transitions observed in neutrinos produced in natural sources like the center of the sun and the earth atmosphere, and also from man-made sources like reactors and accelerators. These oscillations are

LARGE EXTRA DIMENSIONS AT LINEAR COLLIDERS [PDF]

International 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.

Detecting large extra dimensions with optomechanical levitated sensors

European Physical Journal C: Particles and Fields, 2019
Many experiments have been conducted to detect hypothetical large extra dimensions from sub-millimeter to solar system separations. However, direct evidence for such extra dimensions has not been found.

Activated sphalerons and large extra dimensions [PDF]

Physical Review D, 2002
We present a new scenario for the baryon number violation that may take place in models with large extra dimensions. Our idea is interesting because leptogenesis with a low reheating temperature requires an alternative source of the B+L violation to convert the produced leptons into baryons.

Localization of U(1) gauge vector field on flat branes with five-dimension (asymptotic) AdS5 spacetime

Journal of High Energy Physics, 2018
In order to localize U(1) gauge vector field on Randall-Sundrum-like braneworld model with infinite extra dimension, we propose a new kind of non-minimal coupling between the U(1) gauge field and the gravity.

Cosmological perturbations from five-dimensional inflation

Journal of High Energy Physics
It was recently proposed that five-dimensional inflation can relate the causal size of the observable universe to the present weakness of gravitational interactions by blowing up an extra compact dimension from the microscopic fundamental length of ...

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

Journal 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 ...
