Direct detection of dark matter in the form of Weakly-Interacting Massive Particles (WIMPS) is an active field of research. Cryogenic detectors have been in the forefront of the field, due to their exquisite ability to reject backgrounds from interactions of normal matter. In this paper, I describe the current status and future prospects for such experiments. 1. The landscape of dark matter dir...
The search for WIMP-recoil tracks in mica using Atomic Force Microscopy [1] promises important improvements on current exclusion limits. For this to be fulfilled, background sources that could mimic the WIMP-recoil signature must be rejected. In the case of naturally occurring α-recoil tracks, the authors rely on the longer expected depth of their etch-pits, since they result from the sum of 8 ...
The Korea Invisible Mass Search (KIMS) experiment presents new limits on the WIMP-nucleon cross section using data from an exposure of 3409 kg·d taken with low-background CsI(Tl) crystals at Yangyang Underground Laboratory. The most stringent limit on the spin-dependent interaction for a pure proton case is obtained. The DAMA signal region for both spin-independent and spin-dependent interactio...
In the case that dark matter consists of weakly interacting massive particles (WIMPs), dark matter subhalos in the Milky Way could be detectable as gamma-ray point sources due to WIMP annihilations. In this thesis, we study the detectability of dark matter subhalos with Fermi-LAT. We improve on previous work in two ways. Firstly, we take into account the effects of baryons on the density profil...
We show that a supersymmetric neutral Higgs boson with a mass of about 115 GeV and with the other prerequisites required by the LEP Higgs events would be compatible with the detection of relic neutralinos in current set–ups for WIMP direct search. Thus this putative Higgs would fit remarkably well in an interpretation in terms of relic neutralinos of the annual–modulation effect recently measur...
