摘要
We propose an extended version of the gauge-mediated SUSY breaking models where extra SU(2)(L) doublets and singlet field are introduced. These fields are assumed to be parity-odd under an additional matter parity. In this model, the lightest parity-odd particle among them would be dark matter in the Universe. In this Letter, we discuss direct detection of the dark matter and the collider signatures of the model. (C) 2010 Elsevier B.V. All rights reserved.
