Abstract

We investigate phenomenology related to the neutral fields in supersymmetric models with an extra U(1) derived from E6E_6. Our study is concentrated into 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 ZZ^\prime and the LSP may be interesting targets for the study at the LHC. We also discuss features of the ZZ^\prime in the models and its detectability at the LHC.
