, 2016 A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions (CI) or large extra dimensions (LED). The full LHC 2012 proton-proton collision dataset at s = 8 TeV recorded by the

Large hierarchy from extra dimensions [PDF]
Physics Letters B, 2000 We argue that the familiar gauge hierarchy between the fundamental Planck scale M_{Pl} and the electroweak scale M_{W}, can be naturally explained in higher dimensional theories with relatively large radii (R_c > 1/M_{Pl}) extra dimensions. In particular, we show that it is possible that the electroweak Higgs mass at high energies is of the order of

Hidden symmetries from extra dimensions
Journal of High Energy PhysicsIn Kaluza-Klein compactifications, some symmetries of the higher dimensional theory are preserved in lower dimensions, others are broken, and occasionally, there are symmetry enhancements.

Probing large extra dimensions with IceCube [PDF]
, 2014 In models with Large Extra Dimensions the smallness of neutrino masses can be naturally explained by introducing gauge singlet fermions which propagate in the bulk.

Proof of dispersion relations for the amplitude in theories with a compactified space dimension
Journal of High Energy Physics, 2020 The analyticity properties of the scattering amplitude in the nonforward direction are investigated for a field theory in the manifold R 3,1 ⨂ S 1.

Status report on universal extra dimensions after LHC8 [PDF]
, 2014 Although they do not address the hierarchy problem, models with Universal Extra Dimensions have attracted a lot of attention as simple benchmark models characterized by small mass splittings and a dark matter (DM) WIMP played by the Lightest Kaluza–Klein

Helical cosmological magnetic fields from extra-dimensions [PDF]
, 2014 We study the inflationary generation of helical cosmological magnetic fields in a higher-dimensional generalization of the electromagnetic theory. For this purpose, we also include a parity breaking piece to the electromagnetic action.

Updated limits on extra dimensions through torsion and LHC data [PDF]
, 2014 It is well known that the inclusion of torsion in the gravitational formalism, leads to four-fermion interactions. Although the coupling constant of this interaction is strongly suppressed in four dimensions, its value is enhanced in models with n extra ...

Auto-concealment of supersymmetry in extra dimensions [PDF]
, 2014 A bstractIn supersymmetric (SUSY) theories with extra dimensions the visible energy in sparticle decays can be significantly reduced and its energy distribution broadened, thus significantly weakening the present collider limits on SUSY.
