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.

LHC bounds on large extra dimensions [PDF]

open access: yesJournal of High Energy Physics, 2011
We derive new dominant bounds on the coefficient of the effective operator generated by tree-level graviton exchange in large extra dimensions from pp \rightarrow jj data at LHC: M_T > 2.1TeV (ATLAS after 3.1/pb of integrated luminosity), M_T > 3.4 TeV ...

Astrophysical constraints on large extra dimensions [PDF]

open access: yesPhysics Letters B, 1999
In the Kaluza-Klein (KK) scenario with n large extra dimensions where gravity propagates in the 4+n dimensional bulk of spacetime while gauge and matter fields are confined to a four dimensional subspace, the light graviton KK modes can be produced in the Sun, red giants and supernovae. We study the energy-loss rates through photon-photon annihilation,

Light Sterile Neutrinos from Large Extra Dimensions [PDF]

open access: yesPhysics Letters B, 2000
An experimentally verifiable Higgs-triplet model of neutrino masses from large extra dimensions was recently proposed. We extend it to accomodate a light sterile neutrino which also mixes with the three active neutrinos.

Detecting large extra dimensions with optomechanical levitated sensors

open access: yesEuropean 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.

Affleck-Dine baryogensis in large extra dimensions [PDF]

open access: yesPhysical Review D, 2001
Baryogenesis in the models where the fundamental scale is as low as TeV in the context of large extra dimensions is a challenging problem. The requirement for the departure from thermal equilibrium necessarily ties any low scale baryogenesis with that of

Neutrino oscillations and large extra dimensions

open access: yesNuclear Physics B, 2000
Assuming that right-handed neutrinos exist and propagate in some large extra dimensions, we attempt to give a comprehensive description of the phenomenology of neutrino oscillations.

Leptogenesis in Theories with Large Extra Dimensions [PDF]

open access: yesPhysical Review D, 1999
We study the scenario of baryogenesis through leptogenesis in higher-dimensional theories, in which the scale of quantum gravity is many orders of magnitude smaller than the usual Planck mass.

Cosmological Constraints on Theories with Large Extra Dimensions [PDF]

open access: yesPhysical Review D, 1999
In theories with large extra dimensions, constraints from cosmology lead to non-trivial lower bounds on the fundamental scale M_F, corresponding to upper bounds on the radii of the compact extra dimensions.

Black Hole Production and Large Extra Dimensions [PDF]

open access: yesPhysical Review Letters, 2002
Black hole (BH) production at colliders is possible when the colliding energy is above the Planck scale, which can effectively be at TeV scale in models of large extra dimensions. In this work, we study the production of black holes at colliders and discuss the possible signatures.
