We perform an independent analysis of data from the CoGeNT direct detection experiment to quantify the evidence for dark matter recoils. We critically re-examine the assumptions that enter the analysis, focusing specifically on the separation of bulk and surface events, the latter of which constitute a large background. This separation is performed using the event rise-time, with the surface events being slower on average. We fit the rise-time distributions for the bulk and surface events with… 
Search for Low-Mass Dark Matter with the CRESST-II Experiment
There is plenty of evidence from various astrophysical observations suggesting that most of the matter in the universe comes in the form of dark matter. Yet the underlying nature of this dark matter
Global fits of the dark matter-nucleon effective interactions
The effective theory of isoscalar dark matter-nucleon interactions mediated by heavy spin-one or spin-zero particles depends on 10 coupling constants besides the dark matter particle mass. Here we
Complementarity of Searches for Dark Matter
The striking evidence for the existence of dark matter in the Universe implies that there is new physics to be discovered beyond the Standard Model. To identify the nature of this dark matter is a
What is the probability that direct detection experiments have observed dark matter?
In Dark Matter direct detection we are facing the situation of some experiments reporting positive signals which are in conflict with limits from other experiments. Such conclusions are subject to
Composite dark matter and direct-search experiments
The results of the direct searches for dark matter are reinterpreted in the framework of composite dark matter, i.e. dark matter particles that form neutral bound states, generically called “dark
The Past and Future of Light Dark Matter Direct Detection
We review the status and future of direct searches for light dark matter. We start by answering the question: `Whatever happened to the light dark matter anomalies?' i.e. the fate of the potential
Searching for dark matter with DEAP-3600
The DEAP-3600 detector is a single phase direct detection search for particle dark matter. It comprises 3600 kgs of liquid argon, with a 1000 kg fiducialised target volume, surrounded by 255
Light mediators in dark matter direct detections
In an extended effective operator framework, we investigate in detail the effects of light mediators on the event spectra of dark matter (DM)-nucleus scatterings. The presence of light mediators
A systematic halo-independent analysis of direct detection data within the framework of Inelastic Dark Matter
We present a systematic halo-independent analysis of available Weakly Interacting Massive Particles (WIMP) direct detection data within the framework of Inelastic Dark Matter (IDM). We show that,


Chasing a consistent picture for dark matter direct searches
In this paper we assess the present status of dark matter direct searches by means of Bayesian statistics. We consider three particle physics models for spin-independent dark matter interaction with
A CoGeNT Modulation Analysis
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
On the annual modulation signal in dark matter direct detection
We derive constraints on the annual modulation signal in Dark Matter (DM) direct detection experiments in terms of the unmodulated event rate. A general bound independent of the details of the DM
Maximum Likelihood Signal Extraction Method Applied to 3.4 years of CoGeNT Data
CoGeNT has taken data for over 3 years, with 1136 live days of data accumulated as of April 23, 2013. We report on the results of a maximum likelihood analysis to extract any possible dark matter
Bayesian analysis of multiple direct detection experiments
Search for light dark matter in XENON10 data.
The data strongly constrain recent elastic dark matter interpretations of excess low-energy events observed by CoGeNT and CRESST-II, as well as the DAMA annual modulation signal.
Resolving astrophysical uncertainties in dark matter direct detection
We study the impact of the assumed velocity distribution of galactic dark matter particles on the interpretation of results from nuclear recoil detectors. By converting experimental data to variables
Dark-matter harmonics beyond annual modulation
The count rate at dark-matter direct-detection experiments should modulate annually due to the motion of the Earth around the Sun. We show that higher-frequency modulations, including daily
Search for An Annual Modulation in Three Years of CoGeNT Dark Matter Detector Data
Weakly Interacting Massive Particles (WIMPs) are well-established dark matter candidates. WIMP interactions with sensitive detectors are expected to display a characteristic annual modulation in
Dark Matter Search Results Using the Silicon Detectors of CDMS II
We report results of a search for Weakly Interacting Massive Particles (WIMPs) with the silicon (Si) detectors of the CDMS II experiment. A blind analysis of data from eight Si detectors, with a
