Probing the Local Velocity Distribution of WIMP Dark Matter with Directional Detectors

Lee, Samuel K., Peter, Annika H. G.

Understand

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 recoil-energy spectrum, helps break degeneracies in the velocity-distribution parameters.
We also consider the possibility that velocity structures such as cold tidal streams or a dark disk may also be present in addition to the Galactic halo.
Assuming a carbon-tetrafluoride detector with a 30-kg-yr exposure, a 50-GeV WIMP mass, and a WIMP-nucleon spin-dependent cross-section of 0.001 pb, we show that the properties of a cold tidal stream may be well constrained.
