Abstract :
We consider 5D supersymmetric SU(3)×SU(2)×U(1) theories compactified at the TeV scale on S1/Z2 with supersymmetry broken by boundary conditions. Localizing the top quark at a boundary of a fifth dimension by a bulk mass term Mt, reduces the strength of radiative electroweak symmetry breaking. For MtR≈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.
