Generic consequences of a supersymmetric U(1) gauge factor at the TeV scale
- Department of Physics, University of California, Riverside, California 92521 (United States)
We consider an arbitrary supersymmetric U(1) gauge factor at the TeV scale, under which the two Higgs superfields H{sub 1,2} of the standard model are nontrivial. We assume that there is a singlet superfield S such that H{sub 1}H{sub 2}S is an allowed term in the superpotential. We discuss first the generic consequences of this hypothesis on the structure of the two-doublet Higgs sector at the electroweak energy scale, as well as Z-Z{sup {prime}} mixing and the neutralino sector. We then assume the existence of a grand unified symmetry and universal soft supersymmetry-breaking terms at that scale. We further assume that the additional U(1) is broken radiatively via a superpotential term of the form hh{sup c}S, where h and h{sup c} are exotic color-triplet fields which appear in E{sub 6} models. We show that the U(1)-breaking scale and the parameter tan{beta}{equivalent_to}v{sub 2}/v{sub 1} are then both predicted as functions of the H{sub 1}H{sub 2}S coupling. {copyright} {ital 1997} {ital The American Physical Society}
