Direct neutralino searches in the NMSSM with gravitino LSP in the
  degenerate scenario
  In the present work a two-component dark matter model is studied adopting the
degenerate scenario in the R-parity conserving NMSSM. The gravitino LSP and the
neutralino NLSP are extremely degenerate in mass, avoiding the BBN bounds and
obtaining a high reheating temperature for thermal leptogenesis. In this model
both gravitino (absolutely stable) and neutralino (quasi-stable) contribute to
dark matter, and direct detection searches for neutralino are discussed. Points
that survive all the constraints correspond to a singlino-like neutralino.
