PIRSA:11090074  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Certainty And Uncertainty In Dark Matter Searches
Speaker(s): Juan Collar
Abstract: Departing from the context of CoGeNT and COUPP, two direct searches for WIMP dark matter, we will inspect the recent landscape of anomalies observed by these and several other detectors. The aim of this talk is to communicate an appreciation for the subtleties inherent to experimental efforts in thi... read more

PIRSA:11090090  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Status of the XENON100 Dark Matter Search
Speaker(s): Guillaume Plante
Abstract: The XENON100 detector, currently taking data at the Laboratori Nazionali del Gran Sasso in Italy, is a dual-phase xenon time projection chamber used to search for dark matter by simultaneously measuring the scintillation and ionization signals produced by nuclear recoils. These two signals allow the... read more

PIRSA:11090086  ( MP4 Medium Res , MP3 , PDF ) Which Format?
DM-Ice: a Direct Detection Experiment for Dark Matter at the South Pole
Speaker(s): Reina Maruyama
Abstract: I will describe DM-Ice, a direct detection dark matter experiment at the South Pole. The aim of the experiment is to test the claim for an observation of dark matter by the DAMA collaboration by carrying out an experiment with the same detector technology, but in the southern hemisphere. By going to... read more

PIRSA:11090084  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A CoGeNT Modulation Analysis
Speaker(s): Patrick Fox
Abstract: We analyze the recently released CoGeNT data with a focus on their time-dependent properties. Using various statistical techniques, we confirm the presence of modulation in the data, and find a significant component at high (Eee gtap 1.5 keVee) energies. We find that standard elastic WIMPs in a Maxw... read more

PIRSA:11090107  ( MP4 Medium Res , MP3 , PDF ) Which Format?
On the Relation Between the Invisible Higgs Decay and Dark Matter Scattering Cross Sections
Speaker(s): Maxim Pospelov
Abstract: The simplest singlet Higgs-portal dark matter model predicts large/dominant Higgs ->2 DM decay widths in the region of parameter space with m_DM < m_h/2, and Higgs mass below 140 GeV. On the other hand, the direct detection experiments such as Xenon100 put stringent constraints on the ... read more

PIRSA:11090085  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Tidal Streams and Debris Flows: Dark Matter Velocity Substructure and Direct Detection
Speaker(s): Michael Kuhlen
Abstract: High resolution simulations of Galactic Cold Dark Matter halos reveal staggering amounts of substructure, both in configuration and velocity space. In this talk I will focus on the latter. In addition to spatially localized subhalos and streams, I will also discuss so-called debris flows -- incomple... read more

PIRSA:11090103  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Small-Scale Structure of Galactic Dark Matter
Speaker(s): Mark Vogelsberger
Abstract: In my talk I will discuss the relevant astrophysical input for dark matter detection experiments, i.e. the expected distribution of dark matter at the solar position. Based on high resolution N-body simulations I will then show that the formation history of the galactic dark matter halo leaves impri... read more

PIRSA:11090073  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Dark Matter from Minimal Flavor Violation
Speaker(s): Brian Batell
Abstract: Stability on cosmological time scales constitutes one of the few robust guiding principles in the formulation of a theory of dark matter. This suggests the existence of a stabilizing symmetry associated to dark matter. I will explore several examples of stabilizing symmetries beyond the canonical Z_... read more
