Experimental Searches for Non - Baryonic Dark Matter : WIMP Direct Detection
Experimental observations and robust theoretical arguments have established that our universe is essentially non-visible, the luminous matter scarcely accounting for one per cent of the energy density of a flat universe. The distribution of a flat universe (Ω = ΩM + ΩΛ = 1) attributes to the dark energy about ΩΛ ∼ 70%, whereas the matter density takes the remaining ΩM ∼ 30%, consisting of, both...
متن کاملNon–baryonic Dark Matter Searches
The emphasise in this review about non–baryonic dark matter will be on experimental approaches to this fast evolving field of astroparticle physics, especially the direct detection method. The current status of experimental techniques will be reviewed and recent highlights as well as future plans will be introduced.

متن کاملStatus of Direct Searches for WIMP Dark Matter
Astrophysical observations indicate that about 23% of the energy density of the universe is in the form of non-baryonic particles beyond the standard model of particle physics. One exciting and well motivated candidate is the lightest supersymmetric partner particle (LSP), which could be a weakly interacting massive particle (WIMP) left over from the Big Bang. To determine that the LSP is the d...
متن کاملCsI(Tl) for WIMP dark matter searches
We report a study of CsI(Tl) scintillator to assess its applicability in experiments to search for dark matter particles. Measurements of the mean scintillation pulse shapes due to nuclear and electron recoils have been performed. We find that, as with NaI(Tl), pulse shape analysis can be used to discriminate between electron and nuclear recoils down to 4 keV. However, the discrimination factor...
