Dr Marc Schumann (Physik Institut, University of Zurich)02/08/2011, 17:00Direct dark-matter searchesOralXENON100 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...Go to contribution page

Prof. Collar Juan (University of Chicago)02/08/2011, 17:25Direct dark-matter searchesOralRecent 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.Go to contribution page

Dr Daniel Walker (University of Sheffield)02/08/2011, 17:50Direct dark-matter searchesOralWe 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...Go to contribution page

Dr Vitaly Kudryavtsev (University of Sheffield)02/08/2011, 18:15Direct dark-matter searchesOralThe 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...Go to contribution page

Dr Hassan Chagani (University of Minnesota)02/08/2011, 18:40Direct dark-matter searchesOralThe 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...Go to contribution page

Prof. Neil Spooner (University of Sheffield)03/08/2011, 14:00Direct dark-matter searchesOralAn 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...Go to contribution page

Prof. Dan Hooper (Fermilab/University of Chicago)03/08/2011, 14:25Direct dark-matter searchesOralObservations 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...Go to contribution page

Dr Mirco Cannoni (Universidad de Huelva, Spain)03/08/2011, 14:50Direct dark-matter searchesOralWe 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...Go to contribution page

Dr Christopher Savage (Oskar Klein Centre, Stockholm University)03/08/2011, 15:15Direct dark-matter searchesOralWe 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.Go to contribution page

Miguel Pato (ITP Zurich)03/08/2011, 16:00Direct dark-matter searchesOralWe 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...Go to contribution page

Dr Annika Peter (University of California, Irvine)03/08/2011, 16:25Direct dark-matter searchesOralOnce 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...Go to contribution page

Dr Riccardo Catena (Institut fuer Theoretische Physik Heidelberg)03/08/2011, 16:50Direct dark-matter searchesOralAlthough 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...Go to contribution page
