XENON100 is a double-phase (liquid/gas) TPC aiming to directly detect WIMP Dark
Matter. It is in operation underground in the Laboratori Nazionali del Gran Sasso
(LNGS), Italy, and has a measured background which is below all other running Dark
Matter direct detection experiments.
In this talk we will present the newest results from XENON100, obtained from 100
life-days of dark matter...

Recent results from CoGeNT and COUPP will be presented, as well as mention of future
plans for both experiments. A short review of the uncertainties affecting searches
for light-mass WIMPs will be included.

We present an update on efforts to reduce the radon
induced background in
the DRIFT-II direction sensitive WIMP dark matter detector
and the
implications of this for improving sensitivity to spin-
dependent
interactions with a galactic directional signature. New data
including
operation with a fluorine target is presented along with
concepts for
scale-up to a new 24 m3...

The EDELWEISS-II collaboration has carried out a direct search for dark matter
WIMPs (Weakly Interacting Massive Particles) with an array of ten 400 g germanium
detectors operated at cryogenic temperatures of about 10 mK in the Modane
Underground Laboratory (France). The combined use of thermal phonon sensors and
charge collection electrodes with an interleaved geometry enables the...

The Cryogenic Dark Matter Search (CDMS) experiment employs germanium and silicon
semiconductor crystals to perform direct searches of Dark Matter in the form of
Weakly Interacting Massive Particles (WIMPs). Event-by-event discrimination between
electron and nuclear recoils is achieved through simultaneous collection of charge
and phonon signals. The detectors are operated at cryogenic...

An potential observable signature of dark matter linked to our galactic
motion is the annual modulation of the rate of dark matter-nucleon
interactions taking place in an Earth-bound experiment. To search for this
effect, we introduce the concept for a new dark matter experiment using NaI
scintillation detectors deployed deep in the South Pole ice. This experiment
complements dark matter...

Observations from the direct detection experiments DAMA/LIBRA and CoGeNT, along
with those from the Gamma Ray Space Telescope, have been interpreted as possible
evidence of dark matter in the form of relatively light (5-10 GeV) WIMPs. I will discuss
the implications of these observations for dark matter phenomenology and discuss how
it will be possible with future measurements to...

We discuss a suitably normalized form of the isospin momentum dependent structure
functions entering in the
spin-dependent elastic neutralino-nucleus cross section.
We compare these functions with the commonly used ones and discuss their advantages:
in particular, these allow in the spin-dependent cross section to factorize the
particle physics degrees of freedom from the momentum...

We examine how well direct detection experiments can constrain SUSY models, using the
CMSSM as an example. Various issues that affect those constraints are examined, such
as our limited knowledge of the local dark matter halo and uncertainties in the
parameters describing the proton & neutron structures. We discuss difficulties that
arise in scanning the theoretical parameter space.

We investigate the reconstruction capabilities of Dark Matter properties from future
ton-scale direct detection experiments using several targets. Adopting realistic
values for the exposure, energy threshold and resolution of Dark Matter experiments
which will come online within 10 years, the degree of complementarity between
different targets is quantified. While a measurement of the Dark...

Once weakly-interacting massive particles (WIMPs) are unambiguously detected in
direct-detection experiments, the challenge will be to determine what one may infer
from the data. I examine the prospects for reconstructing the local speed
distribution of WIMPs in addition to their particle-physics properties (mass, cross
sections) from next-generation cryogenic and liquid-noble...

Although there are great expectations from the LHC to shed light on physics
beyond the Standard Model and an eventual embedding of a dark matter
candidate within it, a clean handle on the dark matter puzzle will come only
from direct or indirect detection signals of dark matter particles within
dark matter halos. There are classes of dark matter candidates for which it
is indeed feasible...
