SNO measurements strongly constrain the central temperature of the Sun, to within a precision of much less than 1%. This result can be used to constrain the parameter space of SUSY dark matter particle candidates. In this first analysis we find a lower limit for the WIMP mass of 60 GeV, well above the WIMP evaporation limit of 10 GeV. Furthermore, in the event that WIMPs create a quasi-isotherm...
We study the effects of substructure on the rate of dark-matter annihilation in the Galactic halo. We use an analytic model for substructure that can extend numerical simulation results to scales too small to be resolved by the simulations. We first calibrate the analytic model to numerical simulations, and then determine the annihilation boost factor, for standard weakly interacting massive pa...
We present a new module of the micrOMEGAs package for the calculation of WIMP-nuclei elastic scattering cross sections relevant for the direct detection of dark matter through its interaction with nuclei in a large detector. With this new module, the computation of the direct detection rate is performed automatically for a generic model of new physics which contains a WIMP candidate. This model...
Die digitale Musikproduktion ist ein Gebiet, welches mit seinen komplexen Anwendungen die Entwicklung von Benutzungsschnittstellen regelmäßig vor große Herausforderungen stellt. Hier herrschen meist graphische Bedienoberflächen vor, die dem WIMP-Paradigma verhaftet sind. Eine darüber hinaus gehende Auseinandersetzung zur Einbindung von Post-WIMP-Interfaces in diesem Anwendungsszenario ist bisla...
We describe here the theory behind the language comprehension program Wimp. Wimp understands by first, finding paths between the open-class words in a sentence using a marker passing, or spreading-activation, technique. This paper is primarily concerned with the “meaning” (or interpretation) of such paths. We argue that they are best thought of as backbones of proofs that the terms (words) at, ...
We explore the ability of directional nuclear-recoil detectors to constrain the local velocity distribution of weakly interacting massive particle (WIMP) dark matter by performing Bayesian parameter estimation on simulated recoil-event data sets. We discuss in detail how directional information, when combined with measurements of the recoilenergy spectrum, helps break degeneracies in the veloci...
We report the weakly interacting massive particle (WIMP) dark matter search results using the first physics-run data of the PandaX-II 500 kg liquid xenon dual-phase time-projection chamber, operating at the China JinPing underground laboratory. No dark matter candidate is identified above background. In combination with the data set during the commissioning run, with a total exposure of 3.3×10^...
We consider a phenomenological approach to constraining dark matter interactions with quarks by the exchange of a light mediator particle. We find that, for low WIMP masses, an old beam dump experiment provides stronger bounds than currently obtainable at the LHC with monojet searches. 1 A toy model for light dark matter The search for particle dark matter (DM) benefits from many and diverse ap...
Experimentally have we got what it takes to pursue the direct observation of WIMP interactions down to a sensitivities of a few events /(100 kg)/year? For a Ge target with a low energy threshold (< 20 keVr) this corresponds to a WIMP-nucleon σ ∼ 10cm. A number of recent theoretical papers, making calculations in SUSYbased frameworks, show many (> 5) orders of magnitude spread in the possible in...
