Abstract
We investigate phenomenology related to the neutral fields in supersymmetric models with an extra U(1) derived from . 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 and the LSP may be interesting targets for the study at the LHC. We also discuss features of the in the models and its detectability at the LHC.
