Dark Matter Direct Searches

The channeling of the recoiling nucleus in crystalline detectors after a WIMP collision would produce a larger scintillation or ionization signal in direct detection experiments than otherwise expected. I present estimates of the importance of this effect in NaI, Si and Ge crystals, using analytic models developed from the 1970's onwards to describe channeling and blocking and blocking effect.

The XENON10 Experiment has already reported exclusion limits for spin-independent, spin-dependent and inelastic couplings of nuclei to particle dark matter. Recently, there has been considerable (perhaps, renewed) interest in light-mass $\mathcal{O}(10)$~GeV dark matter candidates. In this mass range, the sensitivity of XENON10 drops sharply, due to the low-energy threshold. The low-energy...

It will be possible to push dark matter direct detection sensitivity to a WIMP-nucleon cross-section 10^-48 cm^2 (equivalent to 1 event/10 tonne/year) using a liquid xenon TPCs of up to 20 tonnes, surrounded by a combination of liquid scintillator and water shielding. I will report on the design studies and hardware tests, from the new LUX-ZEPLIN (LZ) collaboration, that have been conducted...

CUORE is a 1-Ton experiment made of about 1000 TeO2 bolometers.
It will probe the neutrinoless double beta decay (0nuDBD) of 130Te,
a tool to test the neutrino nature and mass.
The experimental technique has been proved in CUORICINO, a 40 Kg
experiment that recently set a new limit on the 0nuDBD half-life.
The excellent energy resolution and the low background of these
detectors will...

The search of the annual modulation in the detection rates that could evidence the presence of galactic dark matter energy depositions in the detector is of utmost interest after DAMA/LIBRA positive result. Other experiment using the same target is required in order to confirm the effect, especially after the recent results from CDMS and CoGeNT. ANAIS is a project to be carried out at the...

The Cryogenic Dark Matter Search experiment (CDMS)
employs a total of 30 germanium and silicon detectors
at the Soudan Underground Laboratory to detect weakly
interacting massive particles (WIMPs) via their scattering
from the target nuclei. Previous CDMS results, released
in December 2009, set the world leading limit on the
spin-independent WIMP-nucleon cross section above
WIMP masses...
