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′, and the LSP may be interesting targets for the study at the LHC. We also discuss features of the Z′ in the models and its detectability at the LHC. © 2007 The American Physical Society., 金沢大学理工研究域数物科学系}, title = {Supersymmetric extra U(1) models with a singlino-dominated lightest superparticle}, volume = {75}, year = {2007} }
