We point out a dramatic new experimental signature for a class of theories with extra dimensions, where quarks and leptons are localized at slightly separated parallel ''walls'' whereas gauge and Higgs fields live in the bulk of the extra dimensions. The separation forbids direct local couplings between quarks and leptons, allowing for an elegant solution to the proton decay problem. We show that scattering cross sections for collisions of fermions which are separated in the extra dimensions… Expand

Majorana neutrinos with split fermions in extra dimensions
We propose new solutions to the neutrino mass problem in theories with large extra dimensions in a thick wall scenario. It has recently been argued that our 3-brane could be a thick wall at theExpand
CP violation in 5D Split Fermions Scenario
We give a new configuration of split fermion positions in one extra dimension with two different Yukawa coupling strengths for up-type, hu, and down-type, hd, quarks at hu/hd = 36.0. The newExpand
Collider phenomenology of extra dimensions
In recent years there has been much interest in the possibility that there exist more spacetime dimensions than the usual four. Models of particle physics beyond the Standard Model that incorporateExpand
Physics Beyond the Standard Model: Exotic Leptons and Black Holes at Future Colliders
The Standard Model of particle physics has been remarkably successful in describing present experimental results. However, it is assumed to be only a low-energy effective theory which will break downExpand
Distributions of charged massive scalars and fermions from evaporating higher-dimensional black holes
A detailed numerical analysis is performed to obtain the Hawking spectrum for charged, massive brane scalars and fermions on the approximate background of a brane charged rotating higher-dimensionalExpand
Gauge-Higgs unification on the brane
From the quantum field theory point of view, matter and gauge fields are generally expected to be localised around branes or topological defects occurring in extra dimensions. Here I discuss a simpleExpand
A small weak scale from a small cosmological constant
A bstractWe 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 thatExpand
Probing Neutrino Models in Extra Dimensions with Muon to Electron Conversion and Other Charged Lepton Flavor Violating Processes
Abstract Among the 27(+2) free parameters in Standard Model(SM) with massive neutrinos, 21(+2) out of them are related to the fermion masses. And most of them have been well measured in the past 50Expand
