| dc.description | We propose a Z_2-stabilised singlino (\barχ) as a dark matter candidate in extended and R-parity violating versions of the supersymmetric standard model. \barχ interacts with visible matter via a heavy messenger field S, which results in a supersymmetric version of the Higgs portal interaction. The relic abundance of \barχ can account for cold dark matter if the messenger mass satisfies M_S \lsim 10^{4} GeV. Our model can be implemented in many realistic supersymmetric models such as the NMSSM and nMSSM. | |
