Directional detection of galactic dark matter

TL;DR

Directional detection leverages the Solar system's galactic rotation to identify dark matter particles by measuring the energy and 3D tracks of low-energy recoils, offering a promising approach to dark matter detection.

Contribution

This paper discusses the potential of directional detection strategies that utilize the Earth's motion to distinguish genuine dark matter signals from background noise.

Findings

Directionality can help confirm dark matter signals.

Measuring 3D recoil tracks is essential for directional detection.

Current detector projects face challenges in measuring low-energy recoils.

Abstract

Directional detection is a promising Dark Matter search strategy. 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 that may be a powerful tool to identify genuine WIMP events as such. Directional detection strategy requires the simultaneous measurement of the energy and the 3D track of low energy recoils, which is a common challenge for all current projects of directional detectors.
