【 摘 要 】

We consider the Inert Doublet Model (IDM) with an additional local gauge symmetry U(1) and a complex singlet scalar to break the symmetry U(1). The continuous symmetry U(1) is introduced to control the CP-conserving interaction instead of some discrete symmetries as usually. We present the mass spectrum for neutral scalar and gauge bosons and the values of the charges under U(1) for which the model could have a candidate to dark matter.
