A Solution to the Hierarchy Problem with an Infinitely Large Extra Dimension and Moduli Stabilization
Z. Chacko, A. E. Nelson
We construct a class of solutions to the Einstein's equations for dimensions greater than or equal to six. These solutions are characterized by a non-trivial warp factor and posses…
Gaugino Mediated Supersymmetry Breaking
Z. Chacko, Markus A. Luty, Ann E. Nelson +1
We consider supersymmetric theories where the standard-model quark and lepton fields are localized on a "3-brane" in extra dimensions, while the gauge and Higgs fields propagate in…
Massive Higher-dimensional Gauge Fields as Messengers of Supersymmetry Breaking
Z. Chacko, Markus A. Luty, Eduardo Ponton
We consider theories with one or more compact dimensions with size r > 1/M, where M is the fundamental Planck scale, with the visible and hidden sectors localized on spatially sepa…
Sterile Neutrinos in E_6 and a Natural Understanding of Vacuum Oscillation Solution to the Solar Neutrino Puzzle
Z. Chacko, R. N. Mohapatra
If Nature has chosen the vacuum oscillation solution to the Solar neutrino puzzle, a key theoretical challenge is to understand the extreme smallness of the ($\sim…
