I review recent developments in the direct and indirect detection of dark matter and new candidates beyond the WIMP paradigm.
We present weakly interacting massive particles (WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment (CDEX), based on data both CDEX-1B and CDEX-10 stages. In nonrelativistic approach, time-integrated annual modulation analyses were used to set new limits for coupling WIMP-nucleon operators at 90% confidence level (C.L.) improve o...
We propose a novel probe of weakly interacting massive particle (WIMP) dark matter (DM) candidates wide mass range which fall short the required annihilation rates to satisfy correct thermal relic abundance, dubbed as miracle-less WIMP. If DM interactions are mediated by an Abelian gauge boson like B-L, its typically remain smaller than WIMP ballpark for very high scale B-L symmetry breaking, l...
We report results from a reanalysis of data from the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory. Data taken between October 2006 and September 2008 using eight germanium detectors are reanalyzed with a lowered, 2 keV recoil-energy threshold, to give increased sensitivity to interactions from weakly interacting massive particles (WIMPs) with masses bel...
The CDMS low ionization threshold experiment (CDMSlite) uses cryogenic germanium detectors operated at a relatively high bias voltage to amplify the phonon signal in the search for weakly interacting massive particles (WIMPs). Results are presented from the second CDMSlite run with an exposure of 70 kg day, which reached an energy threshold for electron recoils as low as 56 eV. A fiducializatio...
The GENIUS proposal is described and some of it’s physics potential is outlined. Also in the light of the contradictive results from the DAMA and CDMS experiments the Genius TF, a new experimental setup is proposed. The Genius TF could probe the DAMA evidence region using the WIMP nucleus recoil signal and WIMP annual modulation signature simultaneously. Besides that it can prove the long term ...
The ArDM project aims at developing and operating large noble liquid detectors to search for direct evidence of Weakly Interacting Massive Particle (WIMP) as Dark Matter in the Universe. The initial goal is to design, assemble and operate a ≈1 ton liquid Argon prototype to demonstrate the feasibility of a ton-scale experiment with the required performance to efficiently detect and sufficiently ...
We developed a three-dimensional gaseous tracking device and performed a directionsensitive dark matter search in a surface laboratory. By using 150 Torr carbontetrafluoride (CF4) gas, we obtained a sky map drawn with the recoil directions of the carbon and fluorine nuclei, and set the first limit on the spin-dependent WIMP (Weakly Interacting Massive Particles)-proton cross section by a direct...
