# Split Fermions in Extra Dimensions and Exponentially Small Cross-Sections at Future Colliders

@article{ArkaniHamed2000SplitFI, title={Split Fermions in Extra Dimensions and Exponentially Small Cross-Sections at Future Colliders}, author={Nima Arkani-Hamed and Yuval Grossman and Martin Schmaltz}, journal={Physical Review D}, year={2000}, volume={61}, pages={115004} }

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
