Halo-Independent analysis of direct dark matter detection data for any WIMP interaction

TL;DR

This paper extends halo-independent methods for direct dark matter detection to all WIMP interactions, enabling model-independent comparison of experimental data without assuming a specific dark matter halo profile.

Contribution

It generalizes the halo-independent analysis method beyond spin-independent interactions to any WIMP interaction type, broadening its applicability.

Findings

Method successfully applied to recent Light WIMP data

Enables comparison without assuming dark matter halo models

Generalizes previous halo-independent analysis techniques

Abstract

The halo independent comparison of direct dark matter detection data eliminates the need to make any assumption on the uncertain local dark matter distribution and is complementary to the usual data comparison which required assuming a dark halo model for our galaxy. The method, initially proposed for WIMPs with spin-independent contact interactions, has been generalized to any other interaction and applied to recent data on "Light WIMPs".
