Radiative Electroweak Symmetry Breaking from a Quasi-Localized Top Quark
  We consider 5D supersymmetric SU(3) x SU(2) x U(1) theories compactified at the TeV scale on S^1/Z_2 with supersymmetry broken by boundary conditions. Localizing the top quark at a boundary of a fifth dimension by a bulk mass term M_t, reduces the strength of radiative electroweak symmetry breaking. For M_t R approximately 1--2, the natural value for the top and bottom squark masses are raised to 500--1200 GeV, and all other superpartners may have masses of the compactification scale, which has a natural range of 1/R ~= 1.5--3.5 TeV. The superpartner masses depend only on 1/R, and are precisely correlated amongst themselves and with the mass of the Higgs boson, which is lighter than 130 GeV.
