Exclusion limits from data of directional Dark Matter detectors

Understand

Directional detection is a promising search strategy to discover galactic Dark Matter.

• Taking advantage on the rotation of the Solar system around the Galactic center through the Dark Matter halo, it allows to show a direction dependence of WIMP events.
• Even though the goal of directional search is to identify a WIMP positive detection, exclusion limits are still needed for very low exposure with a rather large background contamination, such as the one obtained with prototype experiments.
• Data of directional detectors are composed of energy and 3D track of recoiling nuclei.
