Exponentially Small Supersymmetry Breaking from Extra Dimensions
Nima Arkani-Hamed, Lawrence Hall, David Smith +1
The supersymmetric ``shining'' of free massive chiral superfields in extra dimensions from a distant source brane can trigger exponentially small supersymmetry breaking on our bran…
Solving the Hierarchy Problem with Exponentially Large Dimensions
Nima Arkani-Hamed, Lawrence Hall, David Smith +1
In theories with (sets of) two large extra dimensions and supersymmetry in the bulk, the presence of non-supersymmetric brane defects naturally induces a logarithmic potential for…
Neutrino Mass Anarchy
Lawrence Hall, Hitoshi Murayama, Neal Weiner
What is the form of the neutrino mass matrix which governs the oscillations of the atmospheric and solar neutrinos? Features of the data have led to a dominant viewpoint where the…
Flavor at the TeV Scale with Extra Dimensions
Nima Arkani-Hamed, Lawrence Hall, David Smith +1
Theories where the Standard Model fields reside on a 3-brane, with a low fundamental cut-off and extra dimensions, provide alternative solutions to the gauge hierarchy problem. How…
Cosmological Constraints on Theories with Large Extra Dimensions
Lawrence J. Hall, David Smith
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…
Electroweak Symmetry Breaking and Large Extra Dimensions
Lawrence Hall, Christopher Kolda
If spacetime contains large compact extra dimensions, the fundamental mass scale of nature, , may be close to the weak scale, allowing gravitational physics to significantl…
