Baryon-number-violating nucleon and dinucleon decays in a model with large extra dimensions [PDF]

open access: yesPhysical Review D, 2019
It is known that limits on baryon-violating nucleon decays do not, in general, imply corresponding suppression of $n - \bar n$ transitions. In the context of a model with fermions propagating in higher dimensions, we investigate a related question ...

open access: yesJournal of High Energy Physics, 2018
A search for nonresonant excesses in the invariant mass spectra of electron and muon pairs is presented. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS experiment in 2016 ...

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.

Neutrinos in large extra dimensions and short-baseline νe appearance [PDF]

open access: yes, 2017
We show that, in the presence of bulk masses, sterile neutrinos propagating in large extra dimensions (LED) can induce electron-neutrino appearance effects.

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.

Primordial black hole dark matter in the context of extra dimensions [PDF]

open access: yesPhysical Review D, 2022
Theories of large extra dimensions (LEDs) such as the Arkani-Hamed, Dimopoulos&Dvali scenario predict a"true"Planck scale $M_\star$ near the TeV scale, while the observed $M_{pl}$ is due to the geometric effect of compact extra dimensions. These theories

Signatures of Large Extra Dimensions [PDF]

open access: yes, 2004
String theory suggests modifications of our spacetime such as extra dimensions and the existence of a mininal length scale. In models with addidional dimensions, the Planck scale can be lowered to values accessible by future colliders. Effective theories

Large and infinite extra dimensions [PDF]

open access: yes, 2001
The emphasis in the developmet of theories with more than three spatial dimensions has recently shifted towards ``brane world'' picture, which assumes that ordinary matter (with possible exceptions of gravitons and other, hypothetic, particles which ...

Large extra dimensions at the Deep Underground Neutrino Experiment [PDF]

open access: yes, 2016
We investigate the potential of the long-baseline Deep Underground Neutrino Experiment (DUNE) to study large-extra-dimension (LED) models originally proposed to explain the smallness of neutrino masses by postulating that right-handed neutrinos, unlike ...
