The locally supersymmetric geometrical hierarchy model

We examine the locally supersymmetric geometrical hierarchy model at energies below the unification mass, MGU. The superfield content, for which the theory has acceptable values of MGU and sin2[theta]w, is discussed. We show that radiative corrections induce the spontaneous breakdown of SU(2) x U(1) to U(1)EM for a top quark mass of 100-200 GeV. In theories with two color triplet Higgs superfields a lower bound of O(1015-1016 GeV) on the supersymmetry breaking parameter, [mu], is derived.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25083/1/0000514.pd
