két kutatás, amely fényt vethet a sötét anyagra:
Xenon Dark Matter Project
"XENON100 is a new dark matter search experiment, aiming to increase the fiducial liquid xenon target mass to 100 kg with a 100 times reduction in background rate, compared to the XENON10 experiment. XENON100 was funded by NSF to Columbia and Rice universities, together with European funding agency's support to University of Zurich, University of Coimbra and Gran Sasso National Laboratory. UCLA joined the XENON100 effort in April 2008. The current XENON100 detector is in operation at Gran Sasso Underground Laboratory. Its scientific reach is a spin-independent WIMP-nucleon cross section of 2 x 10-45 cm2 by the end of 2009. The most recent status of XENON100 can be found in talks presented by XENON100 members in various conferences."
Cryogenic Dark Matter Search
"Using state-of-the-art cryogenic germanium and silicon detectors, the CDMSII collaboration is searching for weakly-interacting massive particles, or WIMPS, whose discovery could resolve the dark matter problem, revolutionizing particle physics and cosmology. This WIMP direct detection experiment is similar to CDMSI, which was located in a tunnel under the Stanford campus. But CDMSII is located deep underground in the Soudan mine in Minnesota, USA. This location provides vastly improved shielding from cosmogenic events which will reduce interference of known backgrounds particles. This will increase the chances of positively identifying a WIMP signal or will allow better limits to be placed on the interaction cross section of the hypothesized particles. The experiment is now running in the Soudan facility."
