Seminarium Teorii Oddziaływań Elementarnych

Current status of the spin-independent (SI) direct detection experiments may suggest that the WIMP dark matter (e.g. neutralinos in supersymmetric models) would interact very weakly with the nucleons. The so-called blind spots in parameter space correspond to the limit of vanishing SI interaction. In my talk I will discuss several classes of blind spots of the NMSSM and their influence on the relic abundance of Higgsino-singlino dark matter. I will also comment on the spin-dependent experiments, which in the nearest future may become competitive to the SI ones in limiting the parameter space.
