Optimizing WIMP directional detectors
We study the dependence of the exposure required to directly detect a WIMP directional recoil signal on the capabilities of a directional detector. Specifically we consider variations in the nuclear recoil energy threshold, the background rate, whether the detector measures the recoil momentum vector in 2 or 3 dimensions and whether or not the sense of the momentum vector can be determined. We ...
متن کاملProbing the Local Velocity Distribution of WIMP Dark Matter with Directional Detectors
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...
متن کاملWIMP dark matter detectors above 100 K
Of key motivation in the development of detector strategies in the search for Weakly Interacting Massive Particles (WIMPs) is the need to maximize the information obtainable from the expected elastic recoil events so that these can be distinguished from background interactions and systematic errors can be controlled. Low temperature techniques may provide one route. However, most of the detecto...
متن کاملWimp Searches with Superheated Droplet Detectors: Status and Prospects
SIMPLE (Superheated Instrument for Massive ParticLE searches) employs superheated droplet detectors (SDDs) to search for Weakly Interacting Massive Particle (WIMP) dark matter. As a result of the intrinsic SDD insensitivity to minimum ionizing particles and high fluorine content of target liquids, competitive WIMP limits were already obtained at the early prototype stage. We comment here on the...
متن کاملDirectional line detectors in correlated noisy environments
In this research, we present a methodology for extracting very narrow lines in correlated noisy environments. The approach is a generalization of the analysis of variance applied to the symmetrically balanced incomplete-blocks design. It encompasses many well-known algorithms when subjected to more restrictive conditions. The detector is robust and superior to the polynomial-approximation-based...
