PIRSA:C09012 - New Lights on Dark Matter - 2009PODCAST Subscribe to podcast

In the last few years, a new observational window has opened on the dark sector of matter. The recent flood of experimental results on direct and indirect dark matter detection has potentially revolutionized our view of the nature of dark matter. As the non gravitational nature of dark matter may well be revealing itself for the first time, initial results have lead to a reexamination of WIMP physics with the aim of enhancing the annihilation cross section through various means, and encouraged theorists to think of more exotic possibilities. The purpose of this workshop is to bring together leading theorists in this area, as well as representatives of the recent experiments, to encourage the sharing and debating of recent results and approaches to probing and describing the dark matter sector.

The LUX Dark Matter Search Program
Speaker(s): Mani Tripathi
Abstract: LUX (Large Underground Xenon) is a two-phase Time Projection Chamber that will instrument 350 kg of Xenon, 100 kg of which will form a fiducially active target for WIMP interactions. It will be deployed at the Sanford Underground Science and Engineering Lab at the Homestake Mine in Lead, South Dakot... read more

Dark Matter Search with CDMS and SuperCDMS
Speaker(s): Wolfgang Rau
Abstract: The Cryogenic Dark Matter Search (CDMS) experiment employs cryogenic ionization detectors to search for nuclear recoils induced by Weakly Interacting assive dark matter particles (WIMPs). A fast readout of the thermal energy deposition and the simultaneous measurement of an ionization signal provide... read more

Signals from the Universe: from DAMA/NaI to DAMA/LIBRA
Speaker(s): Pierluigi Belli
Abstract: The highly radiopure about 250 kg NaI(Tl) DAMA/LIBRA set-up is running at the Gran Sasso National Laboratory of the I.N.F.N.. Results exploiting the model independent annual modulation signature for Dark Matter particles in the galactic halo are presented (exposure of 0.53 ton x yr). The DAMA/LIBRA ... read more

Superweakly interacting massive particles and their direct detection
Speaker(s): Maxim Pospelov
Abstract: KeV-MeV scale dark matter particles with integer spin, very weakly unstable and super-weakly interacting, can produce an observable ionization signal in direct detection experiments. I zoom in on some sensible models and discuss their observational consequences.

Slightly nonminimal Hidden sector,Slightly nonthermal relic abundance, and Indirect Detection
Speaker(s): Ann Nelson
Abstract: I consider a the dark matter relic abundance computation in a model where the dark matter annihilates into a light mediator rather than directly into the standard model. Obtaining the correct relic abundance in such a model may imply a different annihilation cross section than is implied by the usua... read more

Latest results from ZEPLIN-III, a liquid xenon dark matter detector. And a status update on SNOLab.
Speaker(s): Nigel Smith
Abstract: The ZEPLIN-III liquid xenon dark matter detector has completed its first underground science run, with a final exposure after cuts of 128kg.days of data. This has led to a limit on the spin-independent cross section of 7.8e-8pb for a 60GeV mass WIMP. The required techniques to derive this limit will... read more

Novel signatures for direct detection of WIMP dark matter
Speaker(s): Adam Ritz
Abstract: Dark sectors with multi-component WIMP states, with small MeV- to GeV-scale splittings, can lead to more complex signatures in direct detection experiments. I'll discuss some scenarios with excited states charged under either the Standard Model or hidden sector gauge groups, and the ensuing constrai... read more

The DEAP Dark-Matter Search Program
Abstract: The DEAP/CLEAN collaboration will be constructing a 3600-kg single-phase liquid-argon dark matter detector at SNOLAB with sensitivity to 10-46 cm2 for a 100 GeV WIMP. We are currently operating a 7-kg liquid-argon detector (DEAP-1) at SNOLAB. Using DEAP-1 we have made measurements of alpha surface a... read more

Direct Search for Dark Matter with XENON
Speaker(s): Uwe Oberlack
Abstract: The XENON project pursues the goal of directly detecting nuclear recoils resulting from scattering interactions with Weakly Interacting Massive Particles (WIMPs), using a phased approach of increasingly more sensitive experiments. The detector consists of a dual-phase liquid/gas xenon time projectio... read more
