Title: Supersymmetric extra U(1) models with a singlino-dominated lightest superparticle

Abstract

We investigate phenomenology related to the neutral fields in supersymmetric models with an extra U(1) derived from E{sub 6}. Our study is concentrated on the models which have a singlino-dominated neutralino as the lightest superparticle (LSP). If such models satisfy a constraint for dark matter derived from the WMAP data, the lightest neutral Higgs scalar, a new neutral gauge field Z{sup '}, and the LSP may be interesting targets for the study at the LHC. We also discuss features of the Z{sup '} in the models and its detectability at the LHC.
