Constrained standard model from a compact extra dimension
An SU(3)xSU(2)xU(1) supersymmetric theory is constructed with a TeV-sized extra dimension compactified on the orbifold S{sup 1}/(Z{sub 2}xZ{sub 2}{prime}). The compactification breaks supersymmetry leaving a set of zero modes that correspond precisely to the states of the 1 Higgs doublet standard model. Supersymmetric Yukawa interactions are localized at orbifold fixed points. The top quark hypermultiplet radiatively triggers electroweak symmetry breaking, yielding a Higgs potential that is finite and exponentially insensitive to physics above the compactification scale. This potential depends on only a single free parameter, the compactification scale, yielding a Higgs boson mass prediction of 127{+-}8 GeV. The masses of all the superpartners and the Kaluza-Klein excitations are also predicted. The lightest supersymmetric particle is a top squark of mass 197{+-}20 GeV. The top Kaluza-Klein tower leads to the {rho} parameter having quadratic sensitivity to unknown physics in the ultraviolet region.
