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 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 کاملShedding Light on the Dark Sector with Direct WIMP Production
AWeakly Interacting Massive Particle (WIMP) provides an attractive dark matter candidate, and should be within reach of the next generation of high-energy colliders. We consider the process of direct WIMP pair-production, accompanied by an initial-state radiation photon, in electron-positron collisions at the proposed International Linear Collider (ILC). We present a parametrization of the diff...
متن کاملModel-independent WIMP Searches at the ILC
Weakly interacting massive particles (WIMPs) are currently favoured as candidates for Dark Matter, which makes up about 20% percent of the total matter-energy content of the universe. Although the lightest supersymmetric particle, which is the lightest neutralino in many SUSY models, would make a very good WIMP if SUSY with R-Parity conservation is realised in nature, most extensions of the Sta...
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...
