The results from the second run of the Cryogenic Dark Matter Search experiment in the Soudan Underground Laboratory yields new exclusion limits on the coherent WIMPnucleon scalar cross-sections for WIMP masses above 15 GeV/c. Two towers, each consisting of six detectors, were operated in the mine for 74.5 live days, doubling the previous Ge exposure to 34 kg-d after cuts for recoil energies of ...

Astrophysical observations strongly suggest that non-luminous, nonbaryonic components, so called ”Dark Matter”, may constitute most of the matter in the Universe. The Cryogenic Dark Matter Search (CDMS) experiment is designed to detect Dark Matter interaction events through nuclear recoils from elastic scattering. The detector is capable of reading out both phonon and ionization energy of an in...

The Cryogenic Dark Matter Search experiment (CDMS) employs low-temperature Ge and Si detectors to detect WIMPs via their elastic scattering interaction with the target nuclei. The current analysis of 397.8 kg-days Ge exposure resulted in zero observed candidate events, setting an upper limit on the spin-independent WIMP-nucleon cross-section of 6.6× 10 cm (4.6× 10 cm, when previous CDMS Soudan ...

DARWIN (dark matter wimp search with noble liquids) is a design study for a nextgeneration, multi-ton dark matter detector in Europe. Liquid argon and/or liquid xenon are the target media for the direct detection of dark matter candidates in the form of weakly interacting massive particles (WIMPs). Light and charge signals created by particle interactions in the active detector volume are obser...

A potential source of high energy neutrinos is the annihilation of Weakly Interacting Massive Particles (WIMPs) collecting in gravitational potential wells such as the centers of the Earth, the Sun, or the Galaxy. A search for such a WIMP annihilation signal using the Super-Kamiokande (SuperK) detector is presented. Super-K observes 1.1 upward throughgoing muons per day. These events are caused...

Tele-rehabilitation is one of the main domains where Information and Communication Technologies (ICT) have been proven useful to move healthcare from care centers to patients' home. Moreover, patients, especially those carrying out a physical therapy, cannot use a traditional Window, Icon, Menu, Pointer (WIMP) system, but they need to interact in a natural way, that is, there is a need to move ...

A fraction of the dark matter may consist a particle species that interacts much more strongly with Standard Model than typical weakly interacting massive (WIMP) similar mass. Such component could have avoided detection in searches for WIMP-like through its interactions material atmosphere and Earth slow it down significantly before reaching detectors underground. These same can also enhance de...

We study the dependence of the exposure required to directly detect a WIMP directional recoil signal on the capabilities of a directional detector. Specifically we consider variations in the nuclear recoil energy threshold, the background rate, whether the detector measures the recoil momentum vector in 2 or 3 dimensions and whether or not the sense of the momentum vector can be determined. We ...

Abstract We introduce WimPyDD, a modular, object-oriented and customisable Python code that accurately predicts the expected WIMP-nucleus scattering rates in WIMP direct-detection experiments including response of detector. WimPyDD utilises framework Galilean-invariant non-relativistic effective theory, allowing to handle an arbitrary number operators, can perform calculation excepted rate virt...

If weakly interacting massive particles (WIMPs) in bound solar orbits are systematically driven into the Sun by solar-system resonances (as Farinella et al. have shown is the case for many Earth-crossing asteroids), then the capture of high-mass WIMPs by the Earth would be affected dramatically because high-mass WIMPs are captured primarily from bound orbits. WIMP capture would be eliminated fo...
