Extracting Dark Matter Properties Model-Independently from Direct Detection Experiments

TL;DR

This paper reviews model-independent methods to determine properties of WIMPs from direct detection experiments without prior assumptions, relying solely on measured recoil energies across different detectors.

Contribution

It introduces procedures that extract dark matter particle properties independently of assumptions about velocity distribution, mass, or cross sections.

Findings

Methods do not require prior knowledge of velocity distribution.

Recoil energy measurements from different detectors suffice.

Approach enables unbiased dark matter property estimation.

Abstract

In this article I review model-independent procedures for extracting properties of Weakly Interacting Massive Particles (WIMPs) from direct Dark Matter detection experiments. Neither prior knowledge about the velocity distribution function of halo Dark Matter particles nor about their mass or cross sections on target nucleus is needed. The unique required information is measured recoil energies from experiments with different detector materials.
